Your feelings are your feelings and there isn’t really a right or wrong way to feel. But your actions are a choice.
If you need to spend a little time in therapy to sort this through that might not be a bad idea.
Now that your parents are no longer suffering from depression, you have the opportunity to get to really know them without a big black cloud over them ( metaphorically speaking).
Once they’re are in their graves, you can’t get this time back.
If they’ve never really apologized to you that may be what’s fueling your resentment and you should have a straightforward talk with them about it and let them know how you felt as a child.
Your siblings may decide to hang onto their grudge but your relationship with your parents is your own and you don’t have to do the same.
Basically the choice of how to react in the future rather than the past is yours to make.
But what good would it do to keep holding a grudge. Would it benefit you in any way? Its your choice.youre older now now. You’re no longer the hurt child wondering why your parents don’t have time to do fun things with you.
You have a more mature understanding of how debilitating untreated depression can be. As a kid you didn’t realize that. Try to find some room for compassion and understanding.
