Kudos to you for working on getting better! You deserve to be happy and healthy. I am also working on trying to get better. Are you going through this alone or do you have support? If you have support, such as a therapist or nutritionist, I would recommend talking to them about this. If not keep posting here and keep looking ahead. Your body has to get used to this new way of eating. I know for me I struggle with finding balance. I used to suffer from Anorexia, but now that I am eating more, I find that I sometimes tend to overeat. As for feeling tired, when I was restricting heavily, I had much more energy, and now I get tired more easily, but I think we both might need more time to adjust. Plus, midday always kind of drags for me and I'm more likely to nap, which usually just makes it worse for me, but sometimes just have to nap anyway. As for worrying about diabetes, I don't know much about it, but if you are concerned I would recommend talking to a doctor.

Hope that was somewhat helpful! Also, if you need someone to talk to or a little extra support feel free to PM me.
