You’ll be just fine.
It’s nothing more than a symptom of anxiety/an overactive sympathetic nervous system. It’s not permanent, and it WILL go away. Depersonalization is a sign that you’re in fight-or-fight mode, and your human nature is focused on fleeing from danger, which makes you feel “disconnected” from your surroundings and reality. This is normal and something our bodies are naturally wired to do.
Also, the shifting symptoms are definitely characteristic of mind-body symptoms/TMS. It’s referred to as the “symptom imperative,” which is extremely common:

The depersonalization may also be stemming from any emotional work one has been doing, especially if processing pain has been a key component of that work. These feelings will pass.
Stay off the health forums, as they are often filled with horror stories that only lead to heightened anxiety. The mind-body/TMS approach - which people on those health forums often overlook - is the way to go. This means accepting that you are OK, not fearing or obsessing over symptoms like depersonalization, and getting back to fully living life again.
The reason people on those depersonalization forums often don’t get better is because they’re typically very fearful of and/or obsessed with their symptoms, keeping the sympathetic nervous system in overdrive mode. They believe they need to achieve the perfect diet, vitamin and supplement schedule, workout regimin, etc. to heal, when all that’s actually required is some relaxation and a belief that all is well. This also applies to depersonalization from antidepressant withdrawal, cannabis use, etc.
Always remember that the horror stories are not your story. Your story will be one of success!
