Excessive masterbaution. From this!

I am 28 yr old introvert guy,  I have a problem of fapping too much due to which I am facing health issues due to which I lost my job. Actually I am a lonely guy with very less male friends and no female friends at all. I feel very sad when I see everyone having good time with their partner while I am sitting lonely. It not that I tried but whenever I tried to have a friendship with girls they seem not to be very interested in me this made me very sad and some colleagues in my job used to make fun of me for not getting any partner in order to overcome I started fapping but these things made a bad affect on my health.   One female college of mine used me for her attention, but when I proposed her she rejected me saying me dude  you are useless not any of kind. I got very depressed due to this and cry when no one is there. When I see her photo I fantasize her and fap a lot even if she has harmed me a lot. So can anyone suggest me how to overcome this failure and show me light from this
