I revolutionising my life......., but I need help......................... Options

Lol it is kinda embarassing to post here, considering how I believe many problems arent truly problems at all. But doesnt matter, here it goes:

After my school year, I looked back and I saw nothing. Im pretty much a fat, lazy b****** with no friends. Im mediocre in school and I am a couch potato/computer geek. I knew sth gotta change.

I think these are my problems:

1) Computer - This darned invention always seems to lure me in and I lose the sense. Homework? Later. Revision? Can wait. I somehow need to stop my addiction so I can a normal life again.

2) No friends - Well, I am not shy, but the thing is I dont feel I am in any group of friends. I mean we have laughs and work together, but I dont truly feel Im their 'friend'. I dont even think they consider me friend. Many times have I seen them laugh and talk and I want to join them, but I just dont feel a part of them.

3) Unfit - I get stitches by walking 100m and I am sick of myself being a fat lump of meat.
Well, I already do more exercise. I try to run more (1 km) and I now can do 15 push-ups and 30 sit-ups (I know I suck but Im trying to improve) I also eat pretty unhealthily but I dont know any healthy food and stuff.

Summary:

Need help on: Stop computer addiction
Get more friends
choosing exercise to do and I just cant seem to go past what I can do (never can get past 15 push-ups)
Healthy diet

I know Im asking alot and no one is obliged to help. But if you do, I show my eternal gratitude.

THANK YOU!

Sorry I dint update cuz I thought no one cared.........

Well I am ashamed to tell you guys that I havent ran much, not blaming anything but I just dont have any time (rushed homework before summer hols, extra lessons, its still all my fault so I have nothing as excuse) But now its hols so I will run more.

Well I ran yesterday. Only 1.5 km (~ 1 mile) and almost died (heart really fast, not much ache or pain though) I am planning to increase in increments of 1/2 km everytime (nothing significant)

Well I can do 35 sit-ups consecutively but no matter how hard I try, I cant improve from 15 push-ups. I struggle to do them and even mental power proved no use. I guess I just have to work harder.

Well, I dint have time to try out most of the exercise but I cannot manage to do even 1 diamond pushup. Ill formulate a schedule by the end of the week and Ill post it up for comments (if anyone cares)

Question:

Any good exercise for quadriceps, calfs, triceps and biceps?

Well I guess mentally Im fine except there is always a feeling of 'emptiness' inside. I feel like I achieve nothing and I play games to fill it (which make it even worse, bad cycle). Any suggestions to get out of that mentality?

During this short period, I made a few friends (not that close as in we hang out all the time (almost not at all cuz they are the 'popular guys' and Im a 'Crazy chinese study-till-death student', but they are there to mentally support me (they are very nice and mentally deep (if you get what I mean)

I know this is a lot I ask to help and nobody is obliged to help me, but I will appreciate all imput.

I am doing pretty good!
