Well you have made great progress-looking at your profile. I just remember when I was a gangly 6’5 160 kid going into the weightroom for the first time. Some guys on the football team made me feel even more self conscious than I already was.
Now my son is a 15 year old and built like I was, but now I’m 6’6 295. I tell him that he is probably going to run into that guy, the one that makes fun of other people. But I tell him, if the guy is doing that, he may as well wear a sign that says “Hi, I’m a dickhead”. Ignore him and go about your biz.
