OP, I couldn’t read and not offer some small words of hope. I know you’ll be reading everyone’s comments and thinking we’re wrong because we can’t see you/don’t know you/aren’t feeling what you are right now, but I truly honestly mean it when I say there IS a future where you look back at this time and can’t believe you’re as happy as you now are.
There will be a time when this is distant memory, and you’ll recall the feeling and not believe how much things have changed for you, how much happier you are. It truly is possible, I promise.
It sounds ridiculous, but focus on the little things you can do that seem pointless and silly, as it’s those that actually help first, and build into more meaningful change. Like just getting out of the house for 5 mins of fresh air if you wfh, less caffeine, talking to someone for 5 mins (even a few comments here and there on mumsnet if that’s all that feels manageable!), 10 minutes a day reading for a bit of escapism, trying to get one or two early nights. Planning something you enjoy for after work, if it feels like there’s something that might help you get through the day. Even if it’s getting home for a bath, to put some comfort clothes on, to watch a comfort programme/film.
I know it all feels insurmountable and like nothing anyone could suggest will help, but I promise you you’re worth it, you’re worth trying for.
My partner is also feeling really low at the moment and has had similar thoughts, and I’d be more than happy to chat and maybe talk through some things that we’ve done that have helped him, if you want to PM me. Or actually about anything at all!
Sending love x
