I feel so alone and worthless help?

have been through the ringer lately. I had my heart broken so many times that i cant trust no girl anymore. I recently was with a girl who said she loved me and we will be with each other forever and all of a sudden she breaks down and gets all depressed and doesnt talk to me anymore. I was crying i am so depressed and i feel so alone. I am doing bad in school but recently going to a new college starting over to at least do well in school. My job is horrible iam 19 years old and i am a gravedigger at a cemetery. At first i was doing office work but now they moved me to the outside and didnt even give me an option to say no. Im looking for another job but no sucess. with the girl issue though, i feels so alone like comes to a point where i dont want to do anything. I just want to feel that love and to give that love back. Ive been told i was good looking, i am a bodybuilder, i have a good personality ( 2 girls brokwe up with me bc i was too nice like wth) i am a very romantic person and it seems girls dont even look at me like i am some weird bump in the street. I am so lonely like all i want is that love and to feel that i have something to live for and to come back home too. I just dont know what to do. all i want is to be happy and to love life but i am so miserable and sad that i question life. It seems the more i pray To God the worse things become. I see everyone else with their gfs and all i want is that. someone i can talk to and be with always. someone to holdme when i cry and be with. Im getting depressed right now writing this. Like what do i do? Well if anyone can help me itll be nice and i will appreciate it. Thanks
