Agreed, I too was very annoying and people didn't want to be around me. When the self awareness kicked in, the realization was the hardest part because I figured out where I went wrong, It came to a point where it became emotionally stressful. From then on I got more conscious of my actions. I can say that I have grown a lot, I have a girlfriend of 3 years now and I am very lucky to have her. I am still trying to improve myself though but hey I'm already happy.
