I am not diagnosed with depression or any other type of disorder but I really do believe that there is something mentally wrong with me.
I think I have at least 1 of the following:
Depression
Bipolar
Borderline personality
Anxiety
ADHD/ADD (or at least my mom swears I do)
Insomnia

About 2-3 years ago I'd say that I fell into a deep depression. I was about thirteen and I started cutting, I was overdosing on pain killers, and I was going through eating disorder like episodes where anywhere from a week to month if eat barley anything at all (I had literly lost my apatite eating less than 500 cal. A day). My parents sent me to a social worker upon my request and she said that there was nothing wrong with me that I wasn't depressed just having family issues and stopped seeing me within the year. My parents thought I was magically cured just from them knowing and that I'd stop just because of that.

Today,
I still have no ability to cope with everyday life so...
The cutting still happens on occasion...
The drug abuse happens far less than the cutting...
And the "eating disorder" problem happens somewhere in between

I have never been in a romantic relationship
I can count my friends on one hand and I constantly feel like they are stabbing me in the back and/or abandoning me.
My family relationships are kinda the same. I seem alternate who I hate and admire and if I feel like they are abandoning me as well. It has created some fights in all of my relationships.

I cry when I get yelled at or just corrected like a two year old. And I always feel the need to defend myself; I always feel like someone is verbally attacking me.
My grandma and my grandpas sister has depression
I have a cousin who's autistic
And my younger brother is ADHD.

This depressed feeling that I've had for as long as I can remember gets worse at night. It's also when I'm most likely to have a mental breakdown and get in trouble.
I can't sleep no matter how tired I am. I get anywhere between 1-5 hours a night if I'm lucky. If I'm supper lucky I can get 8 but then I just want to sleep more because my body's not use to getting that much sleep and it is so deprived of it.

My grades are terrible. My motivation switches about as fast as my relationships. Ill get motivated and organized one min and not care about doing anything the next.

I'm sick and tired of feeling this way and I'm not sure what is wrong with me.
I have tried telling family members but they say I'm just being a teenager. My doctor (who can't tell the difference between a bug bite and hives. He doesn't care enough to actually look). Says its normal.

This post was originally supposed to be about the one sentence about the depression getting worst at night but I got carried away sorry.
Any advice is helpful.
