Would you share with us what antidepressant you were on last year. It sounds like it helped you and got you through the school year. I agree that seeing your therapist is a good idea. Don't let this get out of hand when you may be able to stop the spiral now.
AS for your obsession, even older grandmothers dream of movies stars, my favorite being Johnny Depp.
Some times it take several attempts to get a person on the right antidepressant. I know it did for me. You say you have a lot on your plate right now, I'm afraid you might end up with a lot more on your plate and possibly not able to handle any of it if you don't slow down and take the time to take care of your mental health. Please give it some thought.
