How you say... I feel good after finally getting closure I'm looking for an idiom that describes feeling better after getting closure/some explanation/clarity on a certain issue... whether breaking up with significant other and having a final face-to-face... getting explanation on death of a loved one.. etc.

Any thoughts?
I got 恍然大悟/善始善终/松了口气/释然/如释重负/大彻大悟/冰释前嫌/释然放怀，无复蔕芥/尘埃落定 etc. in mind. But they don't mean the same.
