picking at/playing with belly button

i come back to the internet every once in a  while to see if anyone else has this problem, i’ve struggled with it for a while and now it’s made me severely self conscious. i play with my belly button a lot, im slightly autistic and it’s a form or stimulation to me. i’ve been doing it since i was really young and now it’s discolored and i find it hard to wear crop tops and low waisted pants because of it :( i just wanted to know if anyone else who does this ended up with a discolored belly button and what they did to try and fix it. i’ve been looking into getting it bleached or piercing it to distract from it. i’ve been trying to get more comfortable with my body since it’s one of my biggest insecurities, but people always feel the need to point it out as if i don’t know it there. i just wanna try and make it better. pls comment and give some recommendations on what to do :0 !!
