You're only making it worse by whining about it. There are people here who do jump on you because of what you post, seeing as what you post is the only thing they can go on to see what you're really like, so my advice to you is to
1. Post intelligently. Spell check your posts, use correct grammar, and just make sure your points are clear, valid and non-confusing.
2. Dont't be mean and/or insultive or disrespectful. You only make yourself more dislikable if you're rude and basically a prick to people on the forums.
3. Last but not least. Stop whining. Whining gets you nowhere. It's the worst thing one can do at your position. Use the time you spend depressed and sad about not having friends here and use that time to actually go out there and work at it. Don't be lazy.
Now. I'll leave you one of my favorite quotes forom the legendary Nike
"Just do it" Have fun and be good ^_^
