First thoughts as a guy who used to be 25 pounds underweight

I've been lifting for about six months now, very concerned with my outcome. I constantly looked in the mirror and felt the same every time... "I'm still skinny" I thought. People used to tell me my arms looked nice or comment on how strong I was (girls complimenting, usually). I still never felt like my body looked good. I looked in the mirror again and still saw a weak skinny flimsy guy. This happened until today.

Today, I looked in the mirror and thought "I definitely wouldn't want to fight me".
