Hello passthepuck!
I know what you’re talking about because it seems like you are describing the way I used to be!
I have good news - things can change. I recommend you consider the social products - instant honesty, instant openness, these will draw people to you and open both you and them up to each other. Instant Gentleman is another favorite of mine. I would also like you to consider Ammo for attraction, nights out etc. For college parties I can recommend Spaceland.
I suggest you have a good read about these products here in The Mens Guide
Also I suggest you study the art of socializing, and consider studying pick up arts like Mystery and David DeAngelo. Just copying people like this will open up a world of new social habits and opportunities 
Hope to see you on the forum more.
