Focus on getting better right now. You have your life in front of you and once you beat this you will have ample opportunity to pay back to the larger community. Please accept that you don't own anyone anything right now and the best you can do it focus on what you need to get better. Its ok to feel the kindness of others when you are in need.

Also, thanks for being so open. Continuing that openness and building a support group for yourself through that is something which helped me through a similar situation.
