Am I overreacting?

Yesterday, I went to the hairdresser to cut the tips of my hair and to get some much need bangs.....I have long curly hair....this was my first time with the hairdresser being that that one I always go to is on vacation and since I start school again in a few day, I wanted a new look for the rest of my semester. Only to have this women do nothing that I asked for! Nothing, she just cut however she wanted. And I walked away feeling as if she took so much of who I am away from me. I could no longer take it and told her to stop. Today, I had my hair in a bun because I feel insecure about my hair. My mother and sister thought it was okay to humiliate me and make fun of my haircut. I know it’s just hair, and it will be fix on Tuesday. But I really felt like I was being kicked while down....maybe I’m overreacting and am taking to much to heart....What do you guys think?
