The Effects of Constant Rejection

So, long story short, I am constantly rejected. Whether it is from a friend. family member or potential partners.

Everyone tells me that I should be happy that I even have family and friends. and don't get me wrong. I really am! But there are times where they push me out of their lives or treat me like I am invisible. Also, don't get me started on potential romantic partners. I'm tired of being told there is no rush to get married and believe me, I am not rushing into marriage! But that doesn't mean that I still don't deserve to be in a relationship with someone I love and who loves me back. We as humans crave touch and love, and often times I find myself in physical pain from all the loneliness.

Anyone have any advice as to how I can cope with it?
