My Girl friend says i'am coming off insecure how can I change that?

Um, well the biggest issue with insecurity is not realizing that you care wayyyyyyyy too much about what ppl think. SO, stop caring. Practice going out without even looking in the mirror and don't try to examine people's reaction to you, just go with it.

My first year of college I was pretty insecure. I've always been the cool guy within my group of friends and that's what I wanted in college. But there were so many ppl that didn't seem interested in me, I became insecure and tried extra hard to make friends and just made myself look like a loser.

I ended up leaving school and working in a retail store. When I worked there, I was so bummed about school that I didn't care about the social drama happening at work. So eventually, at work, they saw me as the cool guy because i didn't get into everyones business and I just didn't care. That's the biggest secret to fighting insecurity. Stop caring about everything else, except yourself. I no longer made excuses for things I did, even if I made a mistake, I didn't try to cover it up, I just said "well, i'm human and sh*t happens." You have to know in your heart the kind of person you are and be proud of that...and whatever you do, (it's gonna be hard) don't let anyone change you.
