If you are, personally, unhappy, then yes, I think you have a problem.
I've kidded around about some of your fanservice threads, but I don't mind them really. However, you have expressed a lack of self confidence on several occasions. You've said several time that the main reason you like the fanservice stuff so much is because you don't feel comfortable around real women. If you were just joking then don't worry about it. It's not a big deal. However, if you were serious, then I think you're doing yourself a disservice by not trying to make yourself happy. There's nothing wrong with the fanservice stuff unless you're using it as a substitute for social interaction. The same goes for anything, really.
And hey, I get it. I used to have a really bad self image. I was overweight, deeply depressed, and unsure about where I wanted to go in life. I was awkward around people I didn't know. I would use games and movies as substitutes for real world relationships. I figured I was a lost cause. But I wasn't. I invested in myself. I worked out. I bought some nicer clothes. I tried to be less awkward. It wasn't easy. It took about two years of real work. But I got better around people, and became much happier. I was surprised to find out that people liked me. I'll never forget the first time a girl started following me around. The guy who had been so fat, quiet, and awkward in highschool. Or the time I was playing frizbee outside, and some people asked me where the gym was because they said I was the sportiest looking guy around. Me, who spent his time watching anime. It was sort of surreal. I had spent my entire life as a kind of outcast and, very slowly, people's view of me had changed. I still felt the same on the inside, but people treated me differently. I found that I liked being around them too. I could actually be pretty funny when I wanted to be, and I started getting more involved with people.
If you're happy with everything, then don't pay any mind to what I said. I don't know you, after all. Who cares what other people think? But if you do feel bad about yourself, then don't. You're always worth the investment, and it's never too late to improve your circumstances. The only person you have to make happy is yourself.
Edit: And as for bad posters, you could do far, far worse. You're nowhere near the worst user we've had here. Damn, you're downright tamecompared to some people.
