Welcome back, and I'm glad to hear you are in a better place mentally these days. Your mental health is just as important as your physical health, and now that you are ready to deal with the physical side of things, you're here.
Perhaps you can try to incorporate healthier choices into the routines you are establishing. If you are reconnecting old relationships (and building new ones) suggest going for a stroll rather than meeting for coffee. Heck, you could get the coffee to go and do both at once!
Small changes can make a big difference in the long run. Pick one healthy, happy thing you'll do today, do it, and be proud! Learn to love the little victories, because the ladies at 3FC are happy to celebrate them with you.
