I have to agree with the above post. Parents are soooo good at denial. So are family members, often times. Stick with your pdoc and let him know you are doing better socially, but showing signs of mania (Let him know what you bought and for how much. He'll get the picture.) Also, if you haven't, let him know about the writing, if you are still doing it.

You sound like a good candidate for a journal. If you feel funny about writing to no one, Don't title it like a letter. I used to call mine Hmn Notes. They were just things I wanted to get out of my system or tell someone. Writing can be therapeutic, if used properly. Just be sure to keep it hidden when you aren't writing.
