Struggling and I don't even know why.

Let me start off by saying this I am autistic I strive on routines but lately I can't follow one. It's causing me to want to purge more. Now I don't do it super often. But I'm scared that I'm going to start doing it and it will get bad again. I've been trying to lose weight in a healthy way. I've been seeing a dietitian. But I just feel like I'm not losing weight and I just want control again. I have chronic fatigue and I don't know why. My mom thinks I'm lazy but I am just tired. I also tend to be kind of a control freak. And I feel like I can't control what's going on in my life right now. I have hardly any friends. I feel like I'm not supported enough. And I know the people in my life are really trying, wanting me to get better. And I keep trying but I am so depressed and so tired. I should probably see a doctor. I just feel like I don't have the energy for anything. And it makes me feel useless. So to cope I pruge. Any advice would be great.
