Do what? I can't talk to girls I don't know.
Stop obsessing over it, for one.
As I've mentioned elsewhere at other times to other people who have gone through this one (including a couple of people I know in person): People, NTs in particular, can ABSOLUTELY TELL when you're obsessed with finding/meeting girls or having a relationship or something like that (believe me, it shows). Most can also sense high levels of jealousy. Often, either of these things will push people away. Gonna make it so much harder to make friends or whatever.
You're spending so much time thinking only about the negative, that the negative has total control over you.
Until you can do something about that... you will not get what you are after.
But also, you're not DOING anything about it. And no, something like a online dating site doesnt count as "doing something", in case you were about to respond with something like that.
"Doing something" in this case isnt going to mean "get a girlfriend", but instead it's going to mean "take back control of yourself and get it together".
Get up, get away from the computer, and DO something. Get a hobby. A hobby that doesnt involve chasing girls. Bring in some positive things that you can actually DO, and improve yourself and your mood in the process. Get out there and exercise. Not to meet girls, but to keep and improve your health. AND your mood. Drink freaking water! I say that all the time and nobody ever listens.
What you SHOULDNT do is just sit on this forum making these threads over and over. All you're doing is creating a "woe is me" echo chamber. Exactly what purpose do you think this has? Reinforcing the negative? That aint helping you.
People here can give advice, sure. But only YOU can make the changes that you need to make. And I'm telling ya, the biggest change you need to make is to STOP OBSESSING OVER IT.
Get up, get away from that computer, and find some activities to do. FORCE yourself. Get yourself out of this rut that you're stuck in. It's more important than you realize. But we cant do it for you.
You can keep making these threads if you want, but no progress will be made through them... keep that in mind.
