I AM THE PROBLEM. I STILL CAN'T DO ANYTHING.

Hi. I am 18 and doing a job with my studies. I am earning good for my age. Half of my salary , i give it to my mother. But it is still not the thing that is making me feel good for myself. I am not being able to give up on my weak personality. I am being very lazy. I just go to job come back use my mobile all night and have a 3-4 hour of bad sleep. I don't have good friends or girlfriend because of my rude behavior. I feel i am on the first phase of that depression thing. Nothing feels worth doing. I don't know where to spend my salary. Don't wanna work on my personality but i need to. I feel fucking lost... Me myself is killing me and i can't do anything.
