baby hairs need to be saved

so a few years back now i was just annoyed and took it out on my baby hairs along the top of my hairline! and i cut them straight off 😳 worst decision of my life and then they started to grow back then people at school start to realise that i had cut them and started picking of me for it so i decided to shave them! take it back before this was the worst decision. anyway so i’ve been shaving the top of my forehead for the past year and a bit and having to wear makeup everyday to cover it and now i’m over it i just want it to be normal again and not feel self conscious all the time and wear makeup everyday, but without the make up i have the worst grey shadow and it looks terrible i’m so frustrated with myself. someone please help me asap on what to do 😪
