i don’t think this pain will ever truly go away.

it does

It will. Just have to give it time, I know it sucks now.

The brain tries to convince you of the worst possible things when it is upset. It whispers evil things to us when we are at our lowest.
The important thing is to NOT listen to it.
Remember: the sand ⏳ is always slipping through the hourglass, which means how you feel currently WILL PASS.
Change is the only constant in life. Therefore you WILL heal, even if you don't believe it right now.
