Are you sure you can’t moan to friends - I’m not saying you are wrong -after all, you know your friends better than I do ;) but it is a normal part of friendship that you can go to each other and have a moan. My favourite past time is moaning it seems at the moment.
I have a few friends that don’t show or talk about difficulties in any detail. They are a bit suck it up and move on. Which is fine, but sometimes I wonder if they feel they can’t moan to me rather than they don’t want to. And I feel I am not being supportive enough. Is there any chance your friends may feel like this?
I’m sorry you feel so bad. It’s like you need something to caputure your attention and make you feel alive.
What about exercise - that may help with tiredness? I’m going to churn out all the usual stuff now - any groups you can join, any books you can read, options for travel, hobbies to take up? New challenge at work? Different work?
I’m not going to be able to phrase this the right way, so bare with me - but do you think you ironically have too high expectations? Ie feel like you should be doing something amazing, surrounded by amazing people all the time (kind of like how Facebook portrays people’s lives?) . If you feel you can’t live up to high expectations that could leave you feeling flat and like life is just one big mundane experience.
I don’t mean it in an - oh just shut up and count your blessings way. But sometimes I catch myself wondering if everyone else’s life is more exciting than mine and when I start thinking like that, I feel flat. A bit of a projection there.
I know GP will likely offer ADs and you don’t want these, but how about a referral to a counsellor. Could be a platform to explore what maybe you could try changing to feel less bad.
