I have been laid off of my job since December 2010 since then I have been getting unemployment and I don't like that I have applied to every job I could think of even the ones were you clean toilets, or making beds, or fast food I have even went on line went into places faxed resumes taken drug test after drug tests I have attended classes on how to do an interview and on how to have a proper resume I DO follow up calls and nothing I have even been on second interviews and still nothing now I getting reviewed all over for my unemployment and now they are telling me that I have worked in the last six months and I havent so now they are sending me to more classes when I try to do right I get nothing and people out there are doing wrong and get everything and I AM GETTING VERY irritated because of this and snapping on my family members especially when they are now trying to deny me of what's rightfully mine what should I DO I even have bills to pay that are late.
