I'm not sure how to start this or what I hope To get out of it. I can't sleep because these thoughts won't go away. I think I really like this girl. I've liked her for 3 or 4 years and I'm pretty sure likes/used to like me too. When ever there's a girl who I truly like, like this girl I can't talk to them and be myself. With girls I don't care about i am very funny and I can pick up a lot of girls but I just don't care about the ones who I can get to want to be with me. Also lately I feel like I'm not as funny. One of the things I pride myself on is being funny, creative, and a little different. I feel like I've lost it. It you read this thank you. It was probably confusing. It was just sort of stream of thought. As you could probably tell I'm a younger guy. I'm really anxious and just want to sleep so I can start a new day.
Sounds like you're letting your worry impede you from being yourself. Stop worrying. Accept the idea that no matter what happens you'll still be around and you'll always have things to either be happy or sad about, so it's really up to you how you feel. The reason you may feel like you're not on top of your game lately may be because you're worrying about whether you are or not. Just fuck it, you're gonna be you regardless of what you are or insist upon yourself, so accept yourself and you'll have nothing to worry about. As far as falling asleep, I know the feeling. Sometimes it takes me upwards of 2-3 hours to actually fall asleep. Try doing as many push-ups as you can, or going for a jog. It helps to actually be physically tired. Listen to soothing music. You CAN clear your mind with a little focus, just dismiss all those random thoughts that keep popping up. Stop listening to them. I know that's easier said then done, but really, everything is. You just gotta do it.
