I felt this way long ago already. Never thought I'd live to see 30. I'm 55 and tired, and I can't say the journey has been pleasant very often. But each day is different, even if only by the slightest thing. I'm not trying to convince you it gets better, but different for sure. A few years ago I couldn't think of anything but the loss of a relationship. Now I'm grateful and can see just how I was used by a narcissist. I couldn't imagine being happy back then without a relationship. I'm not perfectly happy by a long shot, but I don't desire what I used to. I'm glad to have time alone, to play some music even if I'm not great at it. I hope there's something you can find to help you cope a bit with every day that comes. Hugs.
