I think low things of myself and consider myself worthless. . .

What things?

You're questions are a bit vague. Do you think you could give more info, like:

~ What kind of "low things" are you referring to?
~ What "things" have you been through that you think aren't real?
~ You wrote "almost nothing" is wrong with your life. What are the things that ARE wrong with it?
~ When did you first start feeling worthless?

I think u need therapy

But do not turn to cutting. It gets u Labeled and is highly addictive..

I totally feel like this all the time.

You are depressed. Get help. That kind of thinking is classic.

Low things such as, has no meaning in life, completely worthless, i'm just a waste of time and life, and i've felt as if my family has died, since i'm alone all the time it makes it seem real, but it isn't, things that are wrong, I have one friend and idk where he lives, nothing else, and I started feeling worthless since I was 12

^ Yes, I agree with the above questions. I know how you feel though. There is nothing significantly wrong with my life (it is no better or worse than the average person) and yet some days I just feel miserable.
