I Feel So Alone

I just got done creeping on people's Facebook pages of people I used to work with...I look at their profile pictures and what they have visibly posted to strangers to see what they are up to and they seem to have it all....relationships, friends, wonderful families...I don't creep all the time just once every couple of months probably 6 months but when I do I always reflect back on my life and I don't have none of those things. I have never been in a relationship, I have no friends, and my family isn't close like that...I'm not an attractive girl and I am weird from growing up and not being encouraged to talk to people or join social groups/events. I feel so alone and I know that no one likes me because every time I try to be social people just don't accept me.
