it helps to deal with some things, although the things being dealt with in this case are already a bit older

I think, sometimes... we just sort of have to keep going back and processing something over and over, and it means feeling it over and over, and that sucks... because it can feel like not just a step back but a giant leap.

Suddenly all the progress you have made is "gone," you are back "where you started" and it is just fucking unfair, because you already dealt with this; you already moved on from this... but oh hey, says your brain, remember this thing that happened?

I think the thing to hold onto here is that it isn't actually a leap backwards and you are not actually starting from scratch. It just turns out that what you felt before was premature enlightenment. You have still done all the processing and you have still grown from it. You are just not done growing yet; you did not yet get everything you were supposed to get out of it; you did not digest it completely yet. So you are going back for another pass. That's okay. You'll be okay... and you will come out better on the other side.

Do you have any songs that sound positive but the lyrics turn it around completely?

Oh, I love songs like this. Oasis by Amanda Palmer is one of my favourites.

The music is so happy and carefree-sounding, yet it deals with a girl getting raped at a party and having to deal with being shamed for it by pro-life protesters and even her "best friend." I feel like the music and light-hearted atmosphere is a metaphor for the emotional detachment she uses to cope with the situation, and the lyrics also show this... Yeah all this stuff happened but actually look: life is great, I got an autographed photo from Oasis! Eeeeee!

Here is another one I have found more recently and has made me laugh during some really dark times. I hope you enjoy it:
