Here is my story OP, I hope it helps. Of course you feel as if part of you is missing. Your heart has been ripped out.
I’m in a very similar position and have been at absolute rock bottom. There’s a lot of us in your shoes so you’re not alone. It’s coming up to 3 months for me and I’m heartbroken. Totally devastated and betrayed. I am not young. It happens to all ages.
I’ve started therapy (privately) to unpick why my breakup has affected me so badly. I’ve deleted all his social media and given he’s been cheating, we don’t have to be in touch but on a day to day basis it’s crucifying when he was such a massive part of my life. (No kids between us.) Within 2 weeks of our breakup he was in bed with OW.
The first thing I did was book a holiday in the sun all by myself. I went abroad and was the only solo diner in a restaurant full of loved up couples but I made the best of it and enjoyed all the hotel had to offer. The sunshine and swimming was helpful and I made some new acquaintances. I explored my surroundings and challenged myself with a new activity every day. It was hard, but I did it!
The second thing I’ve done is join a local country club. I use the gym & I swim most days. I will sign up for exercise classes too. When I’m not at the club, I walk every day.
It’s a great place for burning off stress, anxiety, panic attacks and anger! I’m not overweight but I want to drop 2 dress sizes and next spring hope to look less heavy and more toned than now. (I’ve had 2 serious surgery’s in recent years and haven’t been able to exercise.) Exercise helps me sleep too.
As soon as I feel emotionally less vulnerable I’ll try a dating site but the jury’s out on that for now because I’m not ready.
My family and friends have been a wonderful support so meet up with others as much as you can. Get yourself out there. Turn to them for comfort and hugs. At times like this you find out who your friends are.
There are lots of helpful relationship gurus on Instagram. I find some of them helpful for giving me insight into my state of mind. It’s like a bereavement, there are stages to go through; depression, anxiety, panic attacks, anger, indifference until one day you wake up and feel more like yourself again. It takes time. It can’t be hurried. Believe me I know. You’ll be fine. Set yourself some goals and go for it.
Keep the faith, better days are coming. The universe has a better plan for you!
