Don't look at yourself as marked down bargain basement merchandise. You're the best "you" there is, and if someone doesn't recognize that, they're not worth your time. Speaking as someone who's been there. Take care of yourself and appreciate your life.

Get out there and start with the little things. You’re a lovely looking woman. Find groups around that match your interests.
Yes, we do date.. heck I’m 47 and date a lot. As you start to get out, the confidence will come.

Look for Agnostic groups on facebook in your community,maybe under free thinkers,they do exist,meet up groups are popular too.

Hmm..I'm 66 years old, taking cannabis oil and recovering from intestinal cancer, a demisexual, and a nonbinary partial transmale who lives as an androgynous female.

My best advice in ending any relationship; cut it off. No more contact, delete/block the person from ALL social media and phones, tell people that "things didn't work out," and NEVER contact them again, or even talk about them with family or friends.

Start attending community and meet up groups, listed online for your area, that match your interests. Go to movies, attend plays, see ballets, whatever you like, either with groups that have similar interests, a friend, or just by yourself, as I do, here in Thailand.

Get outside for a long walk in the early morning and take CBD oil, sold in most health food stores, which seems to cure almost anything, including depression and obesity.

Switch to a more organic natural diet, try to stop drinking sodas, eating red meat, white flour, white sugar, and other processed foods as much as you can, and keep adding more raw, whole, natural foods to your diet.

Don't worry about attracting men..if you are kind and friendly to them at all, they'll come to you. Plenty of lonely divorced men who just want a woman around who is nice to them. Just don't chase and call them yourself..let them do the chasing.
If you aren't some movie star in looks, most men your age aren't either.

But as a demisexual, not chasing men is the easy part, LOL!

But you can lose weight just by taking inexpensive CBD oil.

CBD oil, found in most health food stores, has the opposite effect of THC in cannabis oil - it suppresses the appetite.
It also increases the level of mitochondria in the body, thus thus causing the body to burn more calories.
It stimulates genes and proteins that break down fat cells, reducing the amount of new fat cells that are generated.

CBD oil changes white fatty tissue into beige/brown fatty tissue, which burns energy. Fatty tissue turns from white to brown when it’s cleansed of toxins. Without toxins for white fatty tissue to shield the organs from, there’s no need for it.

People can try different CBD oil dose sizes to find the desired effect on suppressing appetite. For some, 5 mg is fine for them, while others may need as much as 50 mg or more.

I understand what you're going through. I do believe it is more difficult to make new friends when older because most people have developed long term friendships and don't need new ones.

Ive tried to join local meet-ups but my schedule of getting up at 3am and retiring before dark makes socializing impossible in a town where going to bars and church seems to be the only thing to do

I know what you mean from a different perspective. I became a widower at 35. It has been three years since I lost my wife. We were married for 15 years but have known each other for 20. I did not even attempt dating for a year and that for me was a mistake. I wasn't ready and I do not really enjoy the single life very much. I have dated several times and have been in a relationship again that just recently ended. To complicate my problem is that I am very introverted. I have tried meeting people in a wide range of places, but it is hard.

hmmm dunno i gave up at 46 purely because people are annoying to a degree that makes it a chore rather than a joy of course the danger there is you get used to being on your own and become a recluse. I recently got a rescue dog and am both amazed and slightly horrified at the number of people i now have to talk to so maybe thats one way you could at least have interactions with other like minded people or evening classes cooking classes everyones at least got a general starting shared interest other than that its prol gonna be a bit of asshat city im afraid good luck
