If you forget your sins, and you can't confess them, will God send us to hell?

My grandfather is a very strong Catholic and has been teaching me a lot when I was young. Later in life, I let my temper get the best of me and sinned a couple times. I also suffer from mild amnesia now (though some people don't believe me). This amnesia made me forget my sins, and I try to recall them, but I can't seem to be able to. Will, according to the Catholic beliefs, God send me to the lake of tormenting fire when I die?
