I have no idea what to do with myself after Friday. I will graduate out of an outpatient program...
Oh, Gosh! That is a lot of anxiety! I've totally been there. Actually, I was handling my bad issues okay-ish until I graduated and suggenly a lot of new worries and changes were added to my already pretty full plate.
Just that formulation: "I have no idea what I'll do after Friday..." That's insane amount of pressure, like by Friday you should have figured out everything that comes next. Again, I've been there...but that circle has only led me to failures. You DO NOT need to have it figured out by Friday. In fact, tell yourself that you won't, to take some pressure off. If that is an option, take the next week or month off of any pressure and use that time to regroup.
Take a deep breath, and start taking walks or something, and think and figure out the answers to some questions. You know what you can't do right now- good-that's a start. Now, what can you do? You do not have to find purpose+find a job+get a degree all at one time. Think. What would you like doing ideally? Is that an option with your disability? What degrees do you need for that? If income is a priority, while getting whatever degree or finding a purpose, you will need to work something to afford that. You can't work in your specialty or the usual retail/waitress/etc. jobs...is there something that you would be able to work without a lot of issue right now? Do you need a degree for that?
I think, the 2 main things to figure out, is what is your ideal and possible occupation, and if that requires a degree, how you can get money in the meantime. But again, all this can and should be broken down to smaller questions that you can answer. Take your time and answer them. Rushed decisions fueled by anxiety lead to very underpaid jobs. Also I should mention that a lot of my very together non-PTSD friends that graduated the same year as me took 6 months of interview after interview until finding jobs in their field. And even than, they had to start with 3 m internship that was unpaid or paid enough just for transport....So take a deep breath and pace yourself. It's unlikely that you can figure out all those major decisions in just few days, and anxiety never helps to make good decisions.
