Am I failure..just one of those people who will never win.?

So I worked at this job for two months on contract for the summer. I wanted a job there but I was mislead u can say and the one guy I really liked I never got to say goodbye or hint that I liked him. I'm starting to think I'm never going to find anyone. I'm 20 and I have nothing to believe in. We hung out a lot during breaks but I didn't get to tell him I was leaving. I'm unlovable and I'm starting to feel I should give up on romance cause every guy I ever really liked either tried to use me , not like me or **** like this happens and fate steps in. I had everyone trying to get me a job yet nothing. And I never got to say goobye. I feel completly worthless. people say you have like yourseld first but then I do and I then I like somene and then **** happens and then I'm like 'oh **** maybe I'm not as good as a person as I thought.' I mean no one likes me I got mislead by an offer for a job that never happens. People I meet who I reall like leave. It's just not mean to be right
