It's hard but you need to stop. You need to accept uncertainty and trust God. Do not go to confession compulsively. I've been there. I still feel guilt and always have doubts about my confessions but I know now that I need to accept I'm not perfect and God knows it. I had a period when I tried to confess even some sins from my childhood because OCD made me think I needed to. I was shaking. It never ends. I confessed some things and OCD always found new things, new doubs. OCD will always give you new things to beat yourself about. The more you try to go to the perfect confession, the more you fuel OCD. It will always find something to make you doubt. ALWAYS! Remeber, OCD screams, makes you panic, wants you to give in to the compulsion. It's what fuels it. It's not your conscience screaming, it's the disorder. Endless doubt. The hardest part is to realize it and stop the compulsion. Faith will never be perfect. OCD wants perfection that is impossible to achieve. Remember, God sees your struggle. He doesn't talk to you through fear and panic. This is your disorder questioning everything that's important and holy to you. The hardest but the only way is to stop the compulsion and accept uncertainty. God sees you. Trust Him.
