HELP PLEASEEEE!

Hello guys! I'm butterfly... I am 18 years old and I have had Derma since I was a little baby. All memories I have from my childhood have something to do with skin picking & the sad thing is that I still have Derma, but I also have depression, & OCD's (runs in my family), and I really want to stop picking so I can have control on something. I found it really hard cause it is something that has been with me pretty much all my life. I tried Vaseline, long sleeves and covering my scars but nothing seems to work... Any advice? thanks! Btw the areas where I usually pick are my hands (where I have a horrible scar, I have had for a year) my legs and my face:)
