Are you seeing a psychiatrist or therapist? I suggest you talk to one or both of them about this issue. I really think you need to strongly consider getting an official diagnosis and start treatment. I am concerned, like you are, that things could get out of hand. You could escalate into a full-blown manic state, in my opinion.

I would think it would be crucial to make sure to have plenty of any meds for your ailments with you as well.
