I think I have a problem

I have a really bad problem with procrastinating because of how much I love to use forums and do other fun things either online or on electronic devices.
If I'm obligated to do things, then it is easy. I don't want to let people down. So having obligations makes me feel good, because it makes me feel responsible and capable.
But when it just involves me, then I get nothing done. My first thought when I wake up, if I don't have to do anything else, is to turn on the computer. My life practically revolves around it. I don't clean house very much, don't get much exercise. If I'm not working or don't have other plans, it's pretty much a guarantee that I'm on the computer.

I have had what I believe to have been psychological addiction before. I was addicted to a tv series and felt anxious and depressed without it, to the point that I became suicidal. I never saw a professional or anything (is professional help even available for that?), and eventually got through it with support, but I am positive that was addiction. Even when I managed to break the addiction, I still spent some time...recovering, I guess. I felt depressed for a long, long time afterwards.

This, what is going on now, is...different. I don't feel depressed or anxious without the internet. So I don't think I'd call this an addiction. In a way it'd be nice if it was, because then I'd have an excuse, y'know? (Except not, because from when I was actually addicted before, it also gives you a super low self esteem and I know I'd feel infinitely more guilty than I do now.)
But whatever the case what's going on now is still problematic. I don't want to stop using the internet and don't think I need to, but I do need to be more responsible with it. How can I do this? I've been trying for...years, honestly...

i for sure seem to have an Internet "forum" addiction.
I am lonely and always want to talk to someone.
That is why.
