Your ready to deal with your issues now and probably realize every person in this entire world has some sort of issue they are also dealing with inside and hiding it does not help nor get to the root ( no pun intended) of helping you try to understand why you do this to yourself.
Stress is a major factor to our own insecuritys, illnesses and phobias.
We all need to lighten up and not be so hard on ourselves. It's ok not to be perfect cause nobody is. My advice is to just be the best person you can be, that is always enough !
Never let anyone ever make you feel less than !
Who are they to judge you, have they walked a mile in your shoes?
NO
So shut the hell up I say :)

It is so freeing to find yourself so its posible to do you, maybe even for the very first time! You are a human on their way to becoming a brand new person!

Which is unusual because I'm male. I know exactly where it started. A friend told me off you pull out a nose hair you sneeze, I tried it and it worked. Thankfully it's mostly ear, nose and eyebrow hair that bother me. It's annoying AF.
