Hi op sounds like your MH is not good at the moment. I have found that small changes lead to big changes. How have you dealt with the loss of your DM? Do you think you need any counselling? Vitamins are good but don't replace a poor diet
I am younger than you but you describe some of the ways I was feeling at the beginning of this year.
I just made small changes otherwise, it is too overwhelming.
I stopped drinking alcohol completely, it took 3 months to see the benefits but, I lost weight without trying, my skin and eyes look better and my sleep is amazing. As I began to see these changes it prompted me to look after my skin, retinol/sunscreen etc. I also now aim to drink at least 2.5 liters of water per day.
I get out and walk everyday. I make sure I get dressed, put make up on and nice clothes even if I am wfh that day.
I have tweaked my diet to increase more fruit/veg and cut down on meat. I also take a multivitamin/bit B12 and use a magnesium spray at night to help me sleep
Finally I have just started HRT and do kettle bell work outs.
As I have lost weight, gained energy, my anxiety has reduced. I have bought new clothes and love what I wear now. I just feel happier than any other time.
Loads of threads about people worried about loosing their looks/ageing. I feel I look better now as I don't worry about what others think and I feel confident that I am doing the best I can for my body.
I work as a HCP and I see lots of people, some younger than me ageing badly, it's like they have accepted the way they are and made no effort to stay fit/eat healthily. The older people who age well are the ones who stay active. That means something different for everyone. You don't have to run a marathon but you do have to move. Walking is fine and great for MH. Weights are good as you get older to.
It sounds boring, but it's just adjustment to a different part of life so you can continue to enjoy it. Age is just a number but it does require effort. Good luck Op it is possible, results are slow but once you see them it's a huge motivator.
