My c*ck size is making me depressed

So i am 23 and my cock size is around 3.8 inches (normally) and 4.8(When it's hard), since from my childhood i have been always troll by my friends from my school, college. All they ever do was trolling and making fun of me which made me feel so humiliated. It was always affecting me badly but i always think positively until recently, when my ex litreally laugh on me, humiliate me, and make fun of me. her behavior toward me change after it and she leave at the end. I was so sad and frustrated, she tell me that i couldn't satisfy anyone, this and that which put me in a lot pressure, when i ask (indirectly) some of my female frns what they prefer? Than all of them tell they prefer big. So now for few months i have been so frustrated, angry and depressed. My whole confidence is gone, i dont know what to think anymore? Am i reacting overly or other feels same too? If any female can share their view in this topic will be appreciated!
