Respectful answers only. Does Jesus view this as an effort ?

I have read about the lake of fire. I am a devout Christian. I know it exists. And I know that I still sin, despite how hard I try not to. I am frequently angry, enraged sometimes. No one takes the time to really understand me. That would take months. Sometimes I feel like He is all I have left, and my mental self-discipline seems to have been rendered obselete. I pray to Him silently and in whispers all day, the latter when there is no one around. I plead with Him not to punish me with damnation. I have told Him I'm not perfect. I know He is God, and so whatever I think about Him, whether I agree with His judgement or not is absolutely meaningless. I have actually broken into tears pleading with Him not to damn me forever. I know He said He would forgive all those who repented. It seems I have repented of every sin except anger and occasional lies from fear, or even just embellishing to make something more interesting or funny. I can't seem to free myself from those two. I don't drink or smoke, I'm pro-life, I am fully abstinential premaritally, and I hate offending people, even on accident. I have asked Him to give me the strength. But even with His help, I still fail to be single-sinned, or optimally, sinless. I think to myself everyday, "how far does he expect me to repent?" "Have I done enough?" "What if my best isn't enough?" What if He counts the sins even after you ask for forgiveness? What if you can only ask once, and then any sins after that aren't forgiven? I don't know, and He does not have to tell me. Humanity answers to God, not the other way around. I am more terrified of being damned forever than anything else in the world. There is truly nothing more important to me than knowing my fate for sure. Have I gone insane? Or are my concerns legitimate? Anyone who truly knows please tell me. I'm tired of living in fear.
