Hi Brienne welcome to Psych Central. I am sorry you are feeling bad about yourself. It sounds like you have not been able to accomplish everything you wanted to, but you have still achieved things. You still went back to learn a technical skill as you said, and you are still working in the way that you are able to. I am sure you have achieved other things, too. It's not your fault you are dealing with mental illness and that it affected your plans. Are you being treated for bipolar?
