Congratulations for doing what you have done! Be proud of doing the best you can right now.
The mantra I repeat over and over is that I can't take care of anyone else until I take care of myself. I don't think any of the victims in Louisiana would want you to go hungry or fall in to debt to save them. You gift of blood may not directly benefit the Louisiana but it will help someone help and that's a precious gift - no matter who it goes to. Its the same with the food.
I have read that people with depression see the negative rather than the positives. See the positives in what you did today. You've helped many people today and perhaps those people will now help someone in Louisiana. It's all relative.
Take care and God bless you for the things you have done and the fact that you care so much!
