You are brave, and you should be proud of yourself for getting through it, and you have accomplished so much.
My mom's a marathon runner, and when she has an awful, awful, painful race, she always remembers the Bataan Death March or the Cherokee Trail of Tears and that no matter what she's going through, people have gone through far, far worse.
In my family, we are all Eeyore, and we survive things with humor. I hope you can do the same. Best of luck and lots of support to you.
