Can I be honest?
If I met a man who was desperate for a relationship, needy, lonely, anxious and in therapy, I would run a mile. Too much baggage and too much hard work. I want a man who is happy with himself and his life.
So I suspect the opposite is true for you.
I know I should harsh and I'm sorry because I entered my 30s single and it can be shit.
Im certainly no expert and I have never done OLD but this is what I would do.
You say you love your job. So throw yourself into it, get the promotions, the opportunities to do different projects or whatever it is you do. Don't put less effort into your job because it will hamper your OLD. Doing something you enjoy will enhance your life and make you more vibrant and attractive not only to men but to everyone you know.
Take up an activity/hobby. You say the gym is a no go but how about a walking group or ramblers or cycling. A friend of mine does mountain biking and her last 3 serious relationships have been with men she met there. Do something you enjoy not just with men in mind. I suspect ramblers will be older people but it honestly doesnt matter. Just something to get out the house and exercise for you, not just something to meet men.
Ditch the therapist. It encourages self absorption and anxiety IME.
Work on your eating disorder. Eat plenty of healthy food. I find I feel tonnes better if my diet is healthy. I'm not talking about calorie restriction or weight loss here or weird MN style fads. Just eating decent meals, lots of fresh veg, plenty of water etc.
Don't allow yourself to wallow in self pity. If you feel at a loss, put your headphones on and go for a walk. Go swimming. Visit a local attraction. Go to the cinema. Anything, to get you out of yourself.
