Conversational tips? I'll try but you have to promise to really consider what I'm saying.
First of all, I think it helps if you watch movies where there is a guy who knows how to get chicks. When the guy in the movie talks to the girl he wants, pay attention to how he keeps the conversation flowing. Don't focus so much on the exact words that he says. Focus on how he comes up with things to say and try to imitate that technique...
Second, when you're talking with a girl (I'm assuming you know how to START a conversation), try to feed off what the girl says. If she says something like "I went to Las Vegas in the summer", say or ask something about Las Vegas. Act interested. After she replies with another comment, feed off what she just said to keep the convo flowing.
Third, talking to guys DOES help. You said that you don't want or care about guy friends. That's the wrong attitude. Why? Having GUY friends to hang out with you makes you seem like less of a loser, and you'll have an easier time scoring chicks. Also, they can actually help you pick up chicks by putting in a good word for you, introducing you to the girl, being you wingman, etc. They can also give you good girl advice if they're good with the ladies. Focus on making good relationships with EVERYONE, not just women. A guy with only girlfriends and no guy friends is impossible. It's ESPECIALLY IMPOSSIBLE in high school.
Fourth, having CONFIDENCE is not something that you can just DO. I undertand that. When you start having success in life, you'll start to build more confidence in yourself. Confidence makes everything in life (including getting girls) easier. Strive to be more confident because confidence usually translates into happiness which IS the MOST important thing in your life.
Fifth, try to improve yourself in your free time (instead of doing something like playing video games). Lift weights (ladies like strong men...), run (ladies like slim men...), or even practice talking to girls. If you decide to do the last one, you might be able to do this by talking to people on AIM or in a chat room or something. I know it sounds stupid but I think it could help you in your situation. Talk to people your age and try to keep the conversation flowing. This will, in turn, translate to how u talk to people in real life. If you do talk to people online, maybe you could also post what you say here so we can help you in your conversation skills.
Sixth, I typed this whole thing out...meaning that I really DO wanna help you. Helping you doesn't affect my real life in any way because I've never even seen you in real life. I'm just doing this because I like helping people and I like PEOPLE. You might say I'm OPEN. Try to be more OPEN too. Negativity in anything only drives people bad places. Mindset is eveything. Also, don't think my life or anybody's life here is perfect. We got our share of problems too. It's just that we don't always complain about it as much as you do. A real man will feel the pressure, take care of his business, and continue on without making a big deal out of it. I know you have a problem that isn't THAT easy to fix but you really have to stop acting like you're dying because you CAN fix it.
Oh yeah, PS: like that one guy said "LIGHTEN UP" Life isn't worth living if you can't enjoy it and you're always taking everything so serious. AND NO I'M NOT TELLING YOU TO COMMIT SUICIDE (just adding that in case you have a twisted mind). Find a hobby to do when you're not thinking about women. Live you life like a real playa would...(not worrying about women so much)
