Finding a new job after losing one to cancer

FUCK!!!! I'm trying to get a job so I can fix my car & pay my bills but this is really hard! I find it so hard because I got "discharged" (as the applications so nicely put it) from my last one because of problems I was having that were all caused by my awesome cancer *sarcasm*.. I'm a good worker.. I had the second fastest scans (besides my boss, who'd worked there for, like 10+ years or something like that) & my till was never more then a few cents off, if even at all!  So now I need a job & am having a hard time filling out applications because seeing that section causes me to have a panic attack! But I went thru the cancer treatment so this should be a cake walk! Right? Shit... So now I have to go back to my old job place tomorrow & finally spill the beans on what I've been up to for the last 10 months... but I'm all out of my favorite hair ties anyway & have been thinking about going there for more.. Blah! Why does everything have to cost money?? Goddammit!!! I don't want to go back to that store!! But I need a job.. So it looks like I'm going to see my old boss.. FUCK!!! FUCK!!! FUCK!!!
