I do love your example because to me (without getting too spiritual), you had some peace of mind because you dropped into acceptance. We spend life running around trying to manipulate it all to get what we want, and we very rarely experience the complete peace that comes with complete acceptance (like non-attachment in Buddhism).
I know what you mean, but I can't help but think that you are 19 and you're already dictating the things that you must have in order to be fulfilled on your deathbed. That's a lot of pressure! I am not knocking your goals (or goals in general) as they are good goals and they make sense. This may not happen to you but also, what I thought I wanted out of life probably changed 50 times between the ages of 19 and 29, and it is ever evolving. I understand that yours are stuck in a sense because life is on hold, but it's something to consider.
The other thing too is considering what you've said, are you of the view that the whole purpose of life is accomplishment? I'm not saying that it's not important, but what about fun and enjoyment? I do think the absolute lens you speak of is an issue (and it's common with TMS, I have had to improve with it myself). Again, this isn't to discourage you because you should strive for your goals. But I think ironically if you actually pulled back from thinking "If I don't become a judge and have a family then I'm a complete failure and life sucks", then you would probably be in a better position to achieve those things. The universe doesn't respond well to desperation, and I think if you had more flexibility (to think well I want those things and they are great, but life is unpredictable and what if those things don't happen, even through no fault of my own - could I still be fulfilled as a single real estate agent?). That might sound like a silly example, but my point is that to put yourself in a box at 19 and say I won't be fulfilled and happy on my deathbed if I don't get these things, it's a lot of pressure and it is also a tad unrealistic (life is unpredictable and a lot of it is not within our control). I did law and commerce at university and was expecting to become Harvey Specter at 19 (or a high-profile lawyer if that reference doesn't land), and now I'm a chronic pain coach, go figure (and I'm way happier now than I ever was in an office)!
The ironic thing here is that it becomes a self-fulfilling prophecy. Your all or nothing mindset and I'll only be happy if X happens means that symptoms are a complete disaster because they get in the way of these goals (beyond them being awfully uncomfortable, they had added secondary meaning) - this feeds the symptoms and makes it difficult to react with less indifference (which is an important part of recovery). Because of the symptoms, you don't seem to be in a position to make headway on your goals. The thing is I am not trying to gaslight you and I don't want you to try to believe in something that isn't in alignment. We can disagree, I am simply prodding at your current belief system (which I don't believe in myself sure but I also think is not compatible with recovery) to see if that's really what you believe. A lot of our beliefs are simply those of other people, and until they are brought into the light and scrutinised we can't appreciate that actually no that's not what I really believe and I am just going that way out of fear. None of this has the purpose to convince you of anything.
One thing that really hit home when I read it above was when you said "Inherent goodness doesn't mean anything in the grand scheme of things". Do you really believe that? I would say it means everything in the grand scheme of things, in fact thank goodness for those who are inherently good, otherwise the earth probably wouldn't exist by now (there is already so much selfishness and I suppose you could say evil as of now, which is constantly sending us down a diabolical path).
The last thing you said is perfect and the fact that it's giving you stress I don't read as a bad thing. If you feel like love is conditional, then these symptoms basically mean and are a reflection of the fact that you are unlovable (because you can't meet those conditions). One could say that's the ultimate threat (so it makes complete sense to me as to why it's hard to react better to them). What love are you speaking of? I highly doubt your family's love is conditional deep down (even though it may seem like it). The great thing about self-worth and self-compassion is that you're completely in control of that. You get to determine whether that one is conditional. If you're talking about romantic love, without making societal comment do you really want someone to love you based on what you have or what you can provide? This ties into your comment above. If someone loved you for your inherent goodness (which is really what we all want in my opinion), then does it still not mean anything? I'm being hypocritical because in a sense I felt the exact same way as you at your age (and I know that society conditions you to think that your worth is tied to your job and your bank account). This did the same thing to me and my recovery journey in that it got in the way and made me feel even worse in pain. Just because society seems to (in reality I've found it's not really the case and isn't as stereotypical) operate in a conditional and materialistic way doesn't mean that you have to participate, if in fact that doesn't resonate and it isn't your truth. I got to a point with that too where I thought this doesn't seem right to me and doesn't align with my values. I don't want someone to like me solely for what I have, even if that means being alone. Something to consider
