I’m your age, a mum too, and I can relate to some of what you say, not others.
Firstly, why can’t you dance unless the music is from the 80s?! If you stay stuck in the past like that, you will feel old as the past marches further and further away from you. I love to dance too and go to ‘alternative’ dance things and dance to all types of music with people from a range of ages, and yes at some I’m the oldest person there. But I love it.
I don’t recognize what you say about feeling invisible to the general population in normal life. Maybe you were a stunner when younger and got lots of attention, but I don’t really notice much or any ( more likely not any) difference here. I do however, go to various groups where I mix with a lot of people younger than me and older than me, so I am use to chatting with people across generations and not feeling invisible.
Where I do notice a difference is in sexual attention from men. I dislike these threads from women saying they love the loss of this, I don’t. I loved dressing up, going out and getting checked out by men. I loved that feeling of dressing up and looking good. Despite how some on here try to make someone like me feel ashamed for feeling like this.m, I am unashamed by it. It’s perfectly normal for a heterosexual woman to enjoy male sexual attention. The species would have been in trouble if we didn’t! We’ve evolved to like that feeling, and no amount of feminist discourse can undo it. Male sexual harassment is shit, but normal male sexual attention just feels good. I still have a sex drive and I do feel the loss of make sexual
attention. It was fun.
But that doesn’t bother me as much as the physical decline of aging. Eyes needing glasses to see, injuring more easily, recovering more slowly, fitness dropping off a cliff if I can’t exercise for a while, taking longer to recover between gym sessions. And of course, fucking menopause!
In short OP, ageing sucks. I sympathize. But I do recommend living life to the full anyway. Maybe you are feeling invisible because you have stopped initiating interactions with people? One of the people I chat to most at one group is not even 30! I’m literally old enough to be his Mum. But we still get along really well as fellow humans!
