OCD , ANXIETY...Recommend me any doc/medicine

These are the problems i've faced in my life ..I've never consulted a doc..Help me figure out what disorders i've exactly ?

1-I felt like i had no control over saliva secretion in my mouth.EXTREMELY disturbing and i still struggle with it sometimes

2-Irritating sensation of touch..Always felt like table,chair,clothes etc touching my hands,limbs and that irritated me like hell

3-Visual irritations..Felt like i couldn't take my eyes off a design on my T-shirt, my shirt pocket or blinking cursor..

4-During my board exams,developed a strange senstaion of something tight in my neck(Though it went away after exams!)

5-STRANGEST and SCARIEST of all: Felt like my glasses interrupt my vision..Like instead of focussing on stuff i would get disturbed by my glasses coming in way..Gradually modified into headches, felt like i'm in some different world, I couldn't think openly, couldnt talk well,lost confidence, TURNED INTO INTROVERT. While talking with my friends i used to take off my glasses. After 2-3 months of frustation i bought contact lenses.It has been 3.5 years & till now i avoid glasses

RESULT:

1-I used to be very confident in meeting people..But today i try to avoid meeting new people,talking to girls..
2-BIGGEST CONCERN,STUDIES:I was a brilliant student.But today i couldnt sit continuously for 15 mins because i face 225 problems in these damn 15 mins..And instead of focussing on my books,i end up focussing on my problems..Consequently, I runied my career with my own hands..(& i'm runing it further.!!)
3-In EVERY ACT OF MINE i always think that i could have done it in better way & i'm not doing it properly or i'm not able to concentrate..Even while writing ALL THESE there were instances, when i thought my mind isn't working and i couldnt write well..
4-These stuff hit my mind exactly when i'm about to do something very crucial..And i could never do anything up to my potential.

MOST INTERESTING PART:

1-These problems never occur simultaneously
2-There has always been a time when i figured out how to overcome all of above..But after some time,the solutions dont work OR rather what i concluded is that i dont stick to 1 solution
3-THE BIGEST TRUTH WHAT I DISCOVERED IS---
These problems are not at all irritating even if i stick to them..Sometimes i've tried doing nothing but simply facing them and the result was that hardly after 10-15 mins these problems lose their intensity and i feel OK..But the hardest part is i couldnt stop my thoughts :( :( which continuously tend to find solution to problems..

Please help me out :

1-What disorders do i have ?Are they very severe..?
2-Which treatment should i go for,allopathic or homepathic ?
3-Will i be really able to cope up with these problems or should I get used to this life ?
4-Will it take years of treatment to get rid of this or is it simple ?
5-Recommend me any doc in Delhi/Ncr or Lucknow...??
