You have many classic "manic" symptoms. When we're in our manic phases, it feels like we're doing what we want to do, but the mania is often (usually) followed by a crash into depression. Are you getting therapy besides prescriptions? (Like talk therapy with a psychologist or counselor?) You need to get your mood swings under control and get therapy. There may be a part of you saying to yourself that you don't need that, BUT YOU DO. Take care and PLEASE stop using street drugs and having unprotected sex.

Please take care!
