Don't feel bad. I'm 26 and feel the same way. Up until 4 months ago, my relationship was all I had. Now I feel like I have nothing. I have a job, it pays well but doesn't inspire me. I have a college education, but still dont have enough skills to change jobs. I have a house, which is great, but what I really wanted was a home. That went out the window with the Ex. So yea, I know exactly what you mean. Actually, my 26th birthday is in October, and I hope to use that as a springboard to a new productive life.
"Oh Lord it's hard to be humble, when you're perfect in every way. I can't wait to look in the mirror, cause I get better loking each day. To know me is to love me, I must be a hell of a man. Oh Lord it's hard to be humble, but I'm doing the best that I can." Mac Davis
