sad in a rut

so i'm 27. never had a boyfriend never had sex. i am very good at my job (in welfare) but my job (of five years) is coming to an end and i'm worried i'll never get another one because i'm bad at interviews and i look young for my age so i'm never taken seriously. i had anorexia as a very young teenager (13-18? ish?) but i recovered from that and if you met me you wouldn't pick it. i have one friend i met post recovery and they were shocked when i told them. i had a group of friends in school but out-grew them, they are definitely not people i'd choose to be friends with now but i guess loyalty and memories mean something. i had a few friends here and there but i was never their priority only an extra, just the odd person i'd see 1:1 for coffee once every few months. everyone in welfare is female so i never met a boy i liked at work or in university, and i went to a private girl's high school. friends i met in the workplace are mostly 40+ with kids so while i enjoy their company they're not people i see outside of work. i'm developed a complex that nobody likes me or really wants to be my friend or would care if i was gone. i am always the one to text first and send the last text so it's like, nobody really thinks about me. i love work because i'm surrounded by people so i can ignore being lonely at least 9-5. i always think i'd care less about being single if i had a group of friends but it's been literally years of not being invited to anything and going to concerts/movies/shows alone is pretty well the norm.

also i'm (to put it bluntly) so so horny, but i can take care of that part myself and care less about that now; i want a man to take care of me and go on holidays with me and more than anything else, to want me. on paper and the way i present myself to the world is alright: i look at least reasonable, i'm educated, i'm independent, i have a good job, i'm very caring and very loyal and very funny and i'm very liberal in my views. i'm not argumentative or a terrible junk who offends people nothing like that. i've done online dating but i have nothing to talk about and my school friends stay in touch rarely and now they're getting married i'm forced to go to the weddings and i feel so alone. it's to the point where i hate hanging out in groups because i'm the odd one out and nobody considers my feelings. it's new years eve and i'm literally sitting in my bed crying because i have noone who really cares for me except for my parents. they are very invasive people and i'm glad i don't live with them at the moment. my dog died this year and he was the last thing in the world i felt really loved me. i tried meeting people in groups off the internet just to meet SOMEONE and nothing has worked. all i do is go to yoga and work and supermarket shopping and cry myself to sleep every night. i hate my life. how do i fix this
