I HATE BEING SINGLE! Am I Going Nuts?

Today, riding to school, listening to Mariah Carey and burst into tears as "I Don't Wanna Cry" blared from the radio. It has been 10 months and I can still cry on cue. Is that normal? Got me to thinking......since the day I ended my 2.5 year relationship I have been on a binge of searching for a partner with a feverish pace. I honestly think I am going nuts. Every one seems like a prospect and I just want to find what me and my ex had without the problems and long term concerns. It is like my future husband died or something when we broke up and I didn't give myself time to grieve. Literally the day that me and my ex broke up, I was at dinner at the house of a prospective (unworthy) suitor, drinking wine and sharing a first kiss. Which spiraled out into the drama series which ushered in this year. I just didn't want to face the sting of being alone in any head on way and I have been fighting against facing it ever since that day. Yahoo Personals, Match.com, Meeting People Going Out, momentary obsessions with male friends who have been around for years, momentary obsessions with random formerly unnoticed guys at school. All to avoid the reality of the fact that I wake up in the morning and feel a pervasive sadness that nobody wakes me up, there is no one to cook breakfast for or exercise with, to jog in the park with. It saddens me to buy packs of stuff at the grocery store that are too big for me to eat by myself or even the fact that I am in the grocery store by myself. I hate that only my own laundry is in the basket without some huge phantom sock or basketball shorts. I hate that I have to search for things to do on the weekend instead of having pre-determined commitments to a relationship. I detest that every man I meet I wish I could press fast forward and make him do all of those things with me so that I do not feel this tremendous hole in my spirit. I know for those of you who have been subjected to my stories that every week it seems like there is something new for me to be nuts about and every time that falls away, I am left with very raw and new feelings about the failing of my relationship. When the next contrived prospect comes along, I can't help but believe that maybe he is my salvation from this rut. But then, he disappoints me too with inconsistency or odd evasive practices that make me wanna scream, why did I leave my relationship in the first place. This is a desperate circle. Am I going nuts? I really need some therapy I think.
