scared of never finding love again

Hi guys, my bf (well ex bf now) broke up with me kinda out of nowhere, I was more so discarded. Anyways, 3 weeks later I don't miss him, he was a stoner and wasn't the most amazing bf, but I loved him with all the love I had. Now, I am at a stage where I feel the need to cling on to the memory of him because I am so scared I will never be loved again, what if he is the only one who ever finds me pretty and wants me? I'm terrified that that was my only chance at love, and that now at 17 I'll be single forever :frown:
