I know you say you can't take time out for yourself and too busy but in my experience your body will take matters into its own hands and make you physically sick. How is your health? Cold, flu catching stuff. Your immune system and CNS will be firing non stop and you really for everyone around you and your long term health need to sit down with family and talk and see what can be done.
Adding in HRT, drugs and massive lifestyle changes may work, I would also echo the fact you could be peri and your GP sounds shit.
But having had a breakdown at 43 - I was too busy to take a break, running a business, kids, busy social life having fun then wham.
One day driving home I literally started shaking, crying, sobbing, went to bed and had to be very well looked after mentally, I was a mess for 2 months, didn't leave my room, barely ate and recovery has been slow but great.
It was burnout, my body, kidneys, bladder, periods, headaches shakes, temperature regulation just all gave up on me.
I had been working 12-15 hour days in my industry, rushing about.. being all "I've got this" but my brain and body simply couldn't keep up.
Please take some time, be kind to yourself I wouldn't wish what I had on anyone.
