Welcome, Jaxen,.

We can't diagnose here because we aren't doctors, but I can tell you that it sounds very much like some of the symptoms of bipolar illness. However, it could be any number of other things.

My suggestion is that you go in to see a psychiatrist; take the article you have posted here with you and just hand it to him. You will be very surprised at how
completely reassuring they can be and how easily you will be able to converse with him about your document here.

I don't have any question about believing that you might benefit from talking to a psychiatrist. There are things that will help you to learn how to talk about your problem with a specialist, and you might find it to be the best thing you ever did for yourself in your whole life. Please do this for yourself; you will benefit from it greatly.

Good wishes.
