I completely understand where you are coming from. I am a straight female, and I am in my 20's. I feel completely unlovable and even unlikable as I have never been asked on a date, have never had someone be romantically interested in me and its gotten to the point where people around me (friends and family) are wondering if theres something I am doing that makes me so unappealing. Not having been in a relationship at this age is hard enough, but when no one at all seems to like you back it really starts to make you believe that you are somehow the problem. I, like you, feel as if I have nothing to offer anyone.
