Mid life crisis, situational depression or just the menopause?

Hi everyone - can anyone identify with my situation?

I started the menopause when about 50 (now 56), a couple of years after my partner and I coupled up. Once the hot flushes started I found I couldn't cope with bedtime cuddles as I'd instantly flush up and feel really uncomfortable. This has meant our sex life has completely disappeared along with the vital night night cuddle ? And as for sex I'm simply not interested in the slightest.

In the last couple of years my son has returned from living abroad with a wife and baby, they lived with us for a while at the time baby was born (soooo stressful). My relationship with D in Law has deteriorated, don't see my grand daughter much. Another grandchild now on the way. Everybody, and I mean everybody, irritates me, I feel negative and irritable all the time, lonely and detached. I'm driving myself mad, so can totally understand others losing interest. Can't be bothered with anything, nothing spikes my interest anymore and Imfeel like I'm in limbo going nowhere rapidly.

Had been blaming everything on D in Law problems (she is tricky everyone agrees) but I'm not sure it's the whole problem. Feel like I'm going bonkers!

Any advice gratefully received.
