I went to therapy for a couple months during middle school. Probably shouldn't have lied about my self esteem at every occasion... like, I just kinda gave my therapist the impression that I was pretty confident in myself, so I can only imagine what was going through his head when at the end of the very last appointment, he asked what I wanted to do when I grew up, and I just burst into tears. It doesn't help that I still don't have anything I'm passionate enough about to get a career in.
I have never been to therapy, but still don't know what I want to be when I grow up and I am 56 years old. I have been a soldier, a police officer, a warehouse worker, a retirement planner, a railroad conductor, a store clerk and a substitute teacher. I hold two college degrees and am a licensed middle school math teacher. Just do something. If you don't know what you want to do, do something. anything.
