Still not feeling right.

I still don't feel that great. I'm a very happy person and I really do like myself alot. I just feel like when I feel really depressed, that depression feeling locks my usually happy self away. Then, I can't do anything about it until it goes away. I know if I'm hungry I get depressed very easily. It also helps to stay busy, so my mind is thinking of something else instead of sitting there being vulnerable to this depression.Listening to music helps alot too.I take a multivitamin because I basically have low everything. 
Even though I know how to do those certain things, they only work half the time. I try to keep tellin myself that I am a good person and that I am gonna get over this. I can handle it better on some days and other days I can't handle it at all.
I would really just love to talk to people without having to fear how my mood will be in the next 5 seconds. I would especially love to talk to my boyfriend without feeling like that either. He sorta understands and he's been there for me even when we were just friends. He's been there for me thru alot of shit and understands how I am and listens to me and that's why I decided to be with him.
