just thinking on to much things...

Do you ever feel like you just want to shut down your brain and stop thinking on the millions things you're thinking on?
I often feel that way when I can't fall asleep in the evening... (I'm not trying to sleep now)
and now I'm just thinking on a lot of different things, school (should be studying), my economy (pretty broke at the moment) and then all of the relations I have to different people, it's hard =/
and then yesterday I manage to confuse myself.... to explain the story, I have depression, and I used to cut myself but stopped a year ago, but still feel like I want to when I'm really sad and depressed. So yesterday I was on my way home from my cousin (my best friend) and I wasn't really happy, but nothing near really depressed, just kind of somewhere in between, and I just felt the urge to cut myself =/ and it made me confused cause like I said, I only felt it before when I was really depressed =/
no need to worry, I didn't do it, but it made me confused and kind of sad to get that feeling, cause I just feels like theres something wrong with me =/ which it's tecnically is, but hope you know what I mean...
anyway, just wanted to get it out of my head.
take care everyone!
