Until I entered the 9th grade I was fat. I did not have a girlfriend, and all the buddies I used to spend time with were hitting jokes on me, even random girls I approached as acquaintances. It has developed me social anxiety, but I did not come here to cry. Now I entered high school, how can I get rid of my reputation of loser with no love life if I'm not even believed that I hit a girl. "Impossible for him, he scares every girl."

If I wrote about this, can you give me an example of Agree & Amplify for situations when a girl asks you if you have a girlfriend or if you are searching for one, to help me understand them better?
