anyone have longlasting affects of chemo?

i get so depressed sometimes. i cant retain anything anymore, i cant concentrate long enough to carry out things such as getting taxes ready, or even bill paying, if do by some miricle, i loose papers ... i get so frustrated with myself sometimes, i just cry. its not just my mind that has never fully recovered, neither has has my body. im still so tired most of the time, and now i have fibermyalga so they tell me, but its funny that i never had it befor chemo. i have had surgury three times on my breast twice because of the cancer, then three years later because scare tissue had grown in my breast wrapped around my muscles in my side and up into my armpit. i went back to work the following month after my last chemo treatment, i just wanted it all done and get on with my life, big mistake. i had radiation treatments everyday after work for six weeks. i had blisters on the bottom of my feet, and my tonails fell off. at work you had to go downstairs to use the restroom, i was so weak and my leg muscles hurt so bad, i had to rest going down the flight of stairs as well as up the stairs. i quit going to the bathroom after the first day back because i didnt have to strength. driving to work and to the hospital, i would get lost because my brain would take a brake and i would forget where i was. meantime at work my boss was totally sick of me skrewing up at work, hay, you cant do a job if you dont have a brain. my armpit and part of my arm was numb for the first year after my first surgury, when i started to get feeling my arm started to hurt, i had a very active job, and one requirement is to be able to lift 50 pounds, but actually you are lifting up to 200 pounds numerous times during the day. last day at work i was smoothing out bars and i got the most horrible stabbing pains in my arm and that was it, i couldnt use it now it hurts all the time, and when i use it the pain gets stronger until i cant use it at all. i get frustrated with it but not as bad as the brain thing, and what really bothers me is no answers, no diagnoses, its like docs say well your problely depressed, im not a total idiot, this total brain change is not depression, all the changes,except the arm thing, occured from chemo. but doctors dont recognize it or they just ignore me , am i the only one that chemo has affected this way, am i crazey or what?
