I was diagnosed with bipolar disorder about three years ago. Right after that I went through a pretty bad depression. Mostly I was pretty hard on myself for everything I did while manic. School was out for the semester, and I was unable to get a job for the summer because of the med adjustment. I ended up sleeping a lot of the day, and was pretty sad most of the time. I think after a manic episode and having a major diagnosis it takes time to recover.
I did eventually get over the depression part and the medication adjustment period. I took things slowly to accomplish my goals. I went back to school in the fall and took classes, but I did not get a job until the following summer. I slowly started to feel better, and then I started to feel perfectly normal. Most people would not geuss that I suffer from bipolar disorder because I appear just fine. It might take some time to feel like your old self again, but I am sure it will happen eventually.
