It depends what they've done.

I don't know about Jesus but what I will say is that the pain you feel is what you are carrying. Those that hurt you and abused you are either no longer here or do not care and have left you to carry the weight of it. Hanging on to resentment, anger and hate affects you more than anyone so let go. Fill your life with the things you live, find a worthwhile cause and throw your energy into that and hopefully your heart will find the peace that it deserves.

I have struggled for years to forgive all the abuse that was done to me as well. Like you the list is long. I don't feel that we can, all as we can do is ask God to help us.

not forgiving feels like you're chastising yourself

A little thought in the hope it helps. If you can't do anything with it, just put it away. 🙂

Jesus carried all the sins, not merely only from those who would eventually enter heaven. Because of that He is the key to forgiveness, also when we need to forgive others. You talked about duty, which makes it sound like it falls solely on you, but Jesus has also carried this hardship. Please try to do it together with Him. He's on your side.

If a person or people do something seriously wrong to you and refuse to admit to, or apologise for what they did (especially if they are actually breaking laws or perverting the course of justice)...then, there is no forgiveness for them...that is why we have hell!

These abusers though will usually refuse to stop abusing you, but at the same time demand that you forgive them...they also usually deliberately ignore every single signal grace from God Himself on your behalf...

They deliberately and wilfully refuse to accept or understand anything!

But If they confess their sin, and make serious changes to their lives to repent and put an end to that sin, then that is a different matter altogether...
