I commend you on the progress you've made thus far! You should not be so hard on yourself. It took me 9 years to complete my Bachelors degree after I dropped out of college. I've quit jobs for no reason, got fired, and currently live with my mom. To return to graduate school in spite of your anxiety is amazing.

Also, although it doesn't seem like it, as a teacher there was a very good chance you made a positive impact with your students. If you truly loved working with them, I believe they would have received that and appreciated that. And from what it sounds like, you weren't fired. Yes, some of your resignations were due to anxiety and depression. But that wasn't true in some cases. If a school closed down, that had nothing to do with you. I mention this because from what you've written, it sounds like you were an amazing teacher in need of a way to manage your MI while still doing what you were good at.

You've accrued experience, have a college education, and are probably way more skilled and talented than you think.

I agree with Aviza that you should prioritize your MH, get the help you need, and when you feel secure formalize a life plan for yourself where you can develop your career with your MI in mind.

I'm right there with you - I don't trust myself to make the right career choices. and I'm only now learning the process of forgiving myself. In previous threads on this forum I've shared my goals, but I have to be honest about what I can handle and be okay with it. I look at my resume and find despite what I want, I've done well in the restaurant business. If it can afford me the opportunity to get what I really need (time and resources for therapy, self-care, etc) that that's okay. When I approach it this way, I feel less anxious. BUT I still need to seek therapy in order to thrive. It's not about success, it's about thriving and giving myself every chance I can to get better.

You have teaching experience. If you can find a less intensive way to hone your design skills, you could combine these skills and teach others how to design stuff like notecards. diaries, etc. You can even do this online or offer your services through a rec-center program or a website like Skillshare. You can even conduct a small workshop where you teach youngsters graphic design techniques so they can create their own fun stuff. You have plenty of options at your disposal. Just make sure you take care of yourself first, be honest with yourself about what you need, and be okay with the process.
