REALLY down about myself?

[William]

im 19, 5'11, kinda tan, and really DARK brown eyes.
i have came to the conclusion that i give up on dating, and that i am not physically attractive at all.
I have used social networking sites to determine the factor.
1st, if you are going to write "be satisfied and proud to be you or anything like that" please don't write anything at all i beg.

Instagram
1) when i follow random girls that i do not know nor have ever met, they never follow me back, like/comment my photos. if i message them asking them to like my pics they just ignore me or sometimes even block me. yet they post pics of famous men on their page. Sometimes I end up getting into arguments with them, they are mean to me. my friend says don't follow the people, let the people follow you, but i only post selfies and i Tag them with every imaginary tag possible and only get likes from GUYS never GIRLS just guys.

2) Tumblr
when i upload a pic of myself on tumblr, i tag it with every imaginary hashtag possible, nobody ever re-blogs it, likes it or anything. but i see random guys with tattoos all over my dashboard. they get all the re-blogs, why can't i?
are their photos being put on a high followed blog to begin with?

3) Facebook

facebook is a little better but not much, ll kinds of women i do not know like my status (normally 50 likes a status) (i post jokes mainly) i try to present myself as a happy carefree guy on facebook, but women still never inbox me or like my photos. i do not know most of my friends face to face. however, i do get a lot of random status likes

4) Public

When I go out in public i never see any woman looking at me, NEVER at all. No women ever come up to hit on me, nobody looks at me, nobody treats me really special, just that i am another person. I thought attractive people were treated better, and the crowd was around them?

5) I like chubby girls with piercings and tattoos. I am tall and i workout all the time but i am not attracted to fit women. my friends say they could never picture me with someone like that, but thats what i like.

6) I have never had a girlfriend, i do not know what kissing a woman or anything feels like, i've never came close to it. No woman has ever told me i was attractive, i am really shy and afraid to talk to women, i feel there is no way a girl could like me little alone imagine having a sexual relationship with me

7) i am a nice person and i think of other people. I just don't understand, I stare at myself in the mirror for hours a day thinking of what I need to change about myself. I have recently got blue eye contacts, some people tell me i resemble Ian Somerhalder and Chris Hemsworth (2 of the hottest guys on the planet) but women still never approach me?

8) I feel like if i was anyone else but myself i would have a shot with a girl. I don't want anyone to feel sorry for me but that;s really how i feel about myself. The social networking sites have proved to me that women do not like me. and being out in public has also proved it, women never look at me, stare at me, smile at me. i am way to shy to talk to them so please don't tell me to make a move.


If you can help me thank you.
i am not photogenic, but in person people tell me i am beautiful?
