I know the feeling, and you're on the right path with trying to improve yourself. Make sure you're actually improving though, and not just beating yourself up for not being the things you wish you were. that's a mistake I made for a long time; I used to make lists of things I was gonna change about myself, dumb superficial social things like "be quieter so people will think you're mysterious" and "read 3 things a day so you'll be smarter and have more stuff to talk about". But the only things that actually helped in the end were ones like "remember to ask people how they're doing" and "remember one thing about each person you meet that you can ask them about next time you see them". It's almost cynical, but people tend to care about you more once they see that you care about them. Love people, and they'll love you back.
