This is a tough one, and it can be a heavy weight to bear. I'm sorry to hear you're suffering in this way. As someone once told me, "Bitterness is like drinking poison and expecting the other person to die." It sounds like you have been very hurt in the past, and for that, I offer my condolences.

Some advice I would offer is to examine the root of why you reacted the way that you did in these scenarios - what was is it particularly that made you so upset? What is it that you wanted from them that you felt you didn't receive? What would you have wanted them to say/do if you could have controlled the situation? As you self-reflect, I recommend acknowledging the feelings and thoughts that come up and be aware of the sensations of your breath and heart rate. This may at least help you become more aware of what's going on in your heart and mind, which may lead to you being able to address the problem at it's core. I hope you're able to find peace and comfort soon.
