>>3769797If you are on 4chan you have a very high chance of mental illness. This might sound funny but it's actually serious. Very few people would put up with the insanity that goes on here. Being bothered by your past sins can be real - if you did something serious. It may be good to seek help for this, depending on what it leads too. I don't know if your past sins are illegal or not. Only you know that. Sometimes people need to confess them before they feel better. Sometimes everything has been done and you still feel guilt from time to time, or often. The only thing that makes this go away is time. If you're a Christian, like me, you can take your sins to God and ask Him for forgiveness. I recommend this for anyone honestly. If you've never done it before the change can be miraculous, if you're already a Christian and saved it may take a bit more time, you might try repenting (literally changing your mind - choosing not to do anything like that sin again).
It can also be related to OCD.
