need help

i was diagnosed with ocd, i am not taking any medication for it. I got literature on it and among others TTM effects me in a negative way daily, and its getting worse. I didnt think I could be classidied under TTM because i dont deliberatly pull my hair out, my issue is ALWAYS having to have my hair up in a pony tail and i will compulsivly
pick and pull bumps in the back of my head, while my hair is up in a
pony tail it causes it to get very tangled...so tangled that when i
take it down, if im busy or dont have the time to sit and try to detangle it i will just try to smooth it out as miuch
as possible and put it back up in a pony tail, repeating this process
over and over...by the end of the day I have to sit in the shower with
deep conditioner in my hair for 10-30 min and slowly try to comb
through it, trying to loose as least amount of hair as
possible....recently it has gotten worse and at a very fast rate, just
today i had done the routine as i usually do and i dont
realize that i do it more so some days than others, not until i took my
hair down the last time and actually felt how bad it was matted and
tangled (from my scalp to almost the tips of my hair) ....a mental
image would be Frankensteins bride,l it will stand up almost on its
own. I realized today it was one of the few days that i was worried i wouldnt be able to get it out without cutting my hair, and that has happend before. I tried the conditioner but that i always try and that was not working, i went on google and read that baby oil would work, being out of that i used both olive oil and veg oil...gross righty? i tried to slowly pull the strands apare almost peice by peace...it took me 3 differant
sittings because i would get so tired in my fingers and arms, and from
the constant untangling i mead was killing me, by the 3rd setting stioll with the oil in my hair i managed to get a good amount of the snarles out, but i did loose quite abit of hair. my hair is not only falling out because of this but it is also thinnning out, its effecting my daily living that i have to sit and take time just to unmatt my hair,almost like what someone woul dhave to do to get dreds out of there hair. I dont have health ins currently so i am not taking medication, i read about meds they give for ocd, ttm....but i think that my problem has gotten so extreme a medication alone wouldnt help, not onmly is it automatic and such habit i dont even realize it comfots sooths me, i know a pill can take depression away take axiety away and all that but this obsessive habit is effecting me, I am 21 years old and im thinking about trying rogain, there is no bald spots (yet) but my hair is preogresivly getting thinner...i am worried about it in the long run. How is this treated? and does the treatment have a high sucess rate?
