I really need some help

Hi there, I am on here because I need some help. I am 23 years old and I am pretty sure I have a serious problem. Ever since I was very young maybe 5 or 6 I have been biting my nails and picking my toe nails. When I was little I actually chewed the nails off of my toes. Over the years I developed a habit of obsessively looking for and pulling out my split ends in my hair. I always have to pull them apart too and don't stop until I find one I am satisfied from. Around the same time I started doing that I began to pick the skin off of my heels because it is very hard and easy to take off. It gets to the point where I only stop because 1, there is no more skin to pick off or 2, I made myself bleed. When I bleed my heels hurt for days after. I also have a habit of getting toenail clippers and pinching the skin on the back of my fingers. Not really sure what the name of it is, I guess the "backs" of my knuckles where the creases are. I pinch so that I have skin there to pick off. I also have the tendency to clip the skin right above my finger nails. If I don't have clippers I use safety pins or needles to pick my skin. Another thing I do is obsessively look for black heads on my body. I have to squeeze them until I am sure they are cleared out which is to the point that I bleed and they scab over. Never on my face though I don't want people seeing them. I can spend hours doing these things and when I am done with one or can't continue with one, I move on to another. I honestly never thought that there was actually a name to this and that other people did these things too. I have very bad anxiety and never really linked any of this, other than my nail biting, to it. I actually came across this website because I think I have an infection on my heel from skin picking and I was looking for a way to get it better. Too much info? lol If anyone has any advice for me please let me know. I am a Mom and don't want my son to grow up seeing me do this and develop his own habits.
