It's been so long that I hope you don't still feel this way but I'll answer this for anyone who does.
I think this goes hand in hand with a lot of what gets discussed when it comes to self harm and self-destructive behaviors. When you feel hurt emotionally and something feels wrong but you aren't able to get support for that it becomes really easy to just wish that you were physically hurt. On one hand there's the idea that you'll be taken more seriously that way, this is complicated and really depends on where you are and who you're with as many people in physical pain aren't being taken seriously either but the feeling behind it is understandable. I think another cause of it is that even if you know you still wouldn't be taken seriously, there's consequences that you know how to deal with. You don't (normally) feel stupid for being upset when you have a physical injury because that's seen as something understandable to be upset about when emotional pain often just isn't.
The pain itself isn't what's going to help you though but rather taking your emotions themselves seriously and treating the hurt there instead. What you need to do is try and convince yourself that your hurt is already real, even if it isn't visible to everyone else. From there, treat that emotional injury like a physical one. What can you do to treat that pain? Sometimes it's distraction and letting it scab over time, sometimes there's ways to treat yourself that work like medicine, and sometimes it means sitting with the hurt to understand and analyze it and then to get it out somewhere.
I think what I'd also say to ease the type of dysphoria you're experiencing is to make your exomemories a greater part of your identity. Your body is abled now but you can definitely incorporate disabled allyship and activism into your everyday life, even if just in small ways. Take these experiences that mean so much to you and find ways to apply that to your everyday life and it will ease a lot of that fish out of water feeling that a lot of people with exotrauma end up getting.
Rather than viewing your life then and your life now as fully separate, view it as a continuation. You're someone who experienced incredible hardship and who was disabled and now you're suddenly physically healed from all of that and taken out of the situation that you were in. What does the future look like for you at this point? What do you want it to look like?
I know that my exotrauma makes me want to get involved with similar ongoing problems, to the extent that I am able and that is appropriate for me. I think that because there's a lot of focus and discussion around privilege and how it relates to exotrauma that it can feel somehow harmful or disingenuous to seek out people currently going through the same things. There definitely can be a problem of voyeurism where people claiming past lives try to enter a community they're not a part of and that isn't okay in the slightest, of course. But if you view it less as being equivalent to people's material reality right now and more as good a reason to be compassionate as any (because ultimately it doesn't matter why you're helping people so long as you're actually helping) then you're able to build a meaningful community around you with allyship.
That's kind of a lot of easily performative sounding words and this isn't me saying oh you have exotrauma? why aren't you taking action to help real people suffering(tm) or anything. I just think that if you look at your life as being one longer one and try and view your new body and circumstances as an opportunity where relevant, that helps fight the hopelessness that's really common and gives you an excuse to do something important on top of that which can be really cool.
