Hey Cad...I think we all understand how you're feeling. My career keeps me busy, as do family and community obligations. I find that I am quite good at solutions for others, but not for myself. I can bring happy moments to others, but I fail myself.
I make the effort to look around me and see the blessings. There are MANY that I take for granted. When I start to feel self pity, I am reminded that my health can get much worse (and often does). So often times I have to remind myself to be thankful for what I DON'T have.
I have older siblings, but we are not close. I yearn for a close relationship with my sisters who live within 5 miles. They aren't interested. It breaks my heart, but I can't force them to spend time with me. My life could be so different if I had just one close friend to do things with. I don't. My husband is a wonderful companion who actually LOVES to do "chick" things...I love him dearly, but want more.
I don't think any one of us can convince you that life is "worth" living...but we put one foot in front of the other and move forward. It's HARD. It can always get HARD-er, believe me. Look outside yourself. Perhaps find a way to serve others who are less fortunate, the elderly or the indigent.
