Well, the title is self explanatory.

Ever since I have started high school 2yrs ago things have been going downwards. It's like I am sinking deeper and deeper into this pit of idk what to call it but its not good.

I am struggling a lot in all aspects. My mom blows a some 20-27$ every week from her paycheck on booze in order to "cope" (idk with what it is since she never tells me no matter how many times i ask). This is especially bad since we are not doing financially.

I am not really any great either. I am addicted to a video game called enlisted and whenever something happens at school or if I just have a bad day at work or something then I come home and spend hours playing that game, sometimes even time 4-5 in the morning and that too on weekdays. But I can't help it, it's just so soothing to shoot random pixels on a screen and I have no other way to cope with the loneliness and depression except self-harm which I have reduced to a good extent and want to entirely stop. 

Now, obviously this has a negative effect on me and only makes things worse at school and effects grades even further.  

There is only one bully at school but other than that everything is fine but what's worse is that I don't have any friends. I just can't go out of my way to forge relationships and expect people to come to me first even though I know that's not going to happen but I just can't go out there and make new friends, it's just too hard for me.

Idk what to do at this point and my thoughts have become more extreme by the day. I really need advice to get my stuff together. pls.
