Need a boost of self love

I’ve struggled with self esteem and self care for years being left out by friends treated like I was worthless by guys continued knocking my confidence. I can’t find the confidence in me to truly believe I don’t need a guy, making the effort with friends feels like I’m taking one step forward and two steps back, having a conversation is hard enough. I know I need to be able to look myself in the mirror in think “damn you look good” I want to have the confidence to talk to anyone without second guessing myself.

I start university in September and I don’t want a repeat of my high school years any tips on how to change that?
