Weird sense of emptiness

Last weekend, I must honestly say I had a very enjoyable Thanksgiving. Good food, great times with relatives, lots of fun. But that night as I was getting ready to go to bed, I was drained of all joy. I was struck by the thought that unless a miracle happens and I find love and lose my virginity by my 35th birthday, I will only have 2 Thanksgivings left on this earth before I plan to leave. It's a horrible feeling & I couldn't share with any family members
