Picking scalp and nose for blood/scabs, new here

I had never even heard of this website till today when I did a google search for what I do, and I feel like everyone here kinda knows what I am doing. Anyways, I do a couple things, and I think they are kinda like what I see most people talking about? I started doing this thing where I pick the inside of my nose with my pinkie nail super hard till it bleeds, and then once that happens I keep doing it till its flowing really strong, then I just let it flow for a bit then I go to bed, and in the morning I scrape off the blood and eat it. Also, I pick at my head every now and then, making it bleed then licking the blood, then when it scabs up, I repeat and eat the scab. It kinda started when I was 13 or 14, I don't remember why or what was going on around that time, but I started becoming anorexic around 15. Its not a regular thing...in fact I didn't do it for a couple months or so till today, and its been an awful day stress/emotion wise. This along with my anorexic tendencies (im 20 male, 6'9 170) and that the person I usually talk to about all this I cant talk to right now ( :( ) made me think about going to see a professional. I am in college and was thinking about going to the psychology/psychiatry division of the medical center tomorrow and seeing if there is anything they could do, or at least refer me somewhere. Is this a good idea? I don't want to walk in there and them think I am suicidal or something because of all this...I am kinda worried. I also don't know how they would react to me telling them everything, I have only told one person and it was awful. Little rambling, oh well. Is what I described pretty much what everyone else on here does? I have never heard of anyone else doing this
