Hey @Mortimer_3
First, I wanted to welcome you to the forums. Please don't apologise for rambling - that is what this space is for. Sharing your story is often the first step in breaking through that paralysis.
It sounds like you are carrying a massive amount right now. Navigating a new living situation while managing chronic pain and mental exhaustion is draining enough; adding the pressure of finding "mainstream" employment on top of that is a lot for anyone to handle.
If you are neurodivergent (self-diagnosis is valid by the way), masking (trying to appear neurotypical) in a toxic workplace isn't just tiring, it's a recipe for burnout. It makes sense that those environments have not worked for you. Since mainstream environments have been harmful, have you considered remote jobs like data entry, transcription, or even freelance work? These often allow for unmasked work time and better pain management.
Something else I want to quickly bring up is when paralysis hits, the big picture (independence, career, finances) becomes terrifying. Sometimes it helps to focus only on the "next right thing." Today, that might just be resting so your chronic pain settles.
We're all glad that you are here. You don't have to figure out the rest of your life by Tuesday. What is one small thing that feels even 1% manageable today?
