They can't, they won't, could be a bit of both. If you haven't felt your emotions for decades, it can be truly scary. I am going through it, and frankly, it's no picnic, let me tell you, and it's certainly not making my life better in the short run. In fact, it's making it worse.
Take, for instance, meditation. At first, it made me calm down. After a couple of weeks, the tears started, especially whenever anything about feelings and emotions came up. I'd cry, but I wouldn't sob, just tears running down my cheeks, and I was still able to sit still. I knew this could happen and it wasn't abnormal and I was able to just let it be. And then it turned into uncontrollable shaking. I just couldn't keep still. Sitting used to be the easy part for me! I was able to sit still, with a million thoughts racing through my mind. I could no longer do that. I was for real shaking in my chair and my mind was jumping all over the place, of course, and I was crying too. I couldn't finish the meditation, because I was jumping out of my skin.
I hate this so much. I can't even really say whether it's restlessness or anxiety, but it feels very physical. I have no control over it, it starts in my stomach, it gets all tight, something bubbles up through my body, and when it reaches my eyes, the crying begins. Big, fat, ugly sobbing, the works. After a while, it somehow peters out, but I don't really feel better. Sometimes I might feel a lot better about half an hour later.
Sometimes it's not that elaborate. Something triggers me and I feel this weird shiver, and then it stops before it even fully starts and it feels incomplete, somehow. It's so short and sudden that I don't even have the time to choose if I'm going to sit with it or do something or panic or whatever. Like something wants to come out and boom, it's blocked, almost instantly.
To me, it feels like my body is trying to tell me something, but part of me is resisting that. I'm trying to listen, but it's not really going well, and I have no idea what I can do to facilitate that. I'm quite confused, these days.
