Twitching - This is really a start for your healing. Recognizing that your happiness was based on getting the attention, and love of your spouse. This will be allow you to take the step to become a strong independent woman. When this happens the need to tolerate any nonsense from your WS goes away, and you become exponentially stronger. Its quite wonderful.
OK So How to comfort and heal. Things that help you find your center of balance again, and also make you feel good about yourself are what you should focus on.
I would suggest getting a really good set of headphones and download your favorite music to your phone, and start going for walks daily. Enjoy the world around you, notice all the beautiful things, take pleasure from these, flowers, animals, even the pretty patterns cut into peoples lawns.
Find out if there are some yoga or pilates classes near you. Sign up and take em. This is an excellent form of exercise that is not strenuous on your body if you aren't in great shape, and the amount of attention, and focus it takes will clear your mind of all the extraneous nonsense you are dealing with and will help you to feel stronger, and more clear of thought.
Do one nice thing for yourself each and every day. A hot bath, a long walk, reading. A pedi, a mani etc. Do things that you enjoy and make you feel better about yourself, and your appearance.
Then start looking into new hobbies and activities. Try a few that you find interesting. This is how I took up beekeeping. I was always interested in bees, and fascinated by what they can do. Two years of study, and attending local beekeeping club meetings we bit the bullet and got our first hives. Now 5 years later it's a full fledged business, and I love doing it. I also get a kick out of seeing peoples reaction on their face when I say I'm a beekeeper. you get that Really? face. It's fun.
You have the world at your feet all you have to do is take a step into it.
