Not a waste of time! You sound like a very valuable person--you are considerate of your family and friends and concerned about them and your future. Hope you will feel brave enough to write a note to your doctor, take it in and let the doctor read it and see if you can get some help. Might be meds could help you feel better, if it's not life' circumstances that are getting you down. Do write again and let us know how you are doing.

PS. And I'm fine, thank you! Today, anyways, and that's how I take things, one day at a time.
