If you pay, you can guide the sessions more. Lots of counsellors seem to have a method and they’ll approach everyone by working through similar exercises. Mine did that, but I simply asked that we concentrate on X for now and maybe come back to that when we’d worked through X. That’s a polite way of using your money to the best effect as I knew I couldn’t afford endless sessions.
So, in the first session, honestly set out your issues - food, control, whatever - and ask if he/she feels able to help you work through those things. This will also give you a chance to see if the counsellor is the right person for you. It’s important they are.
If you need to starve yourself to control your sugars, that’s not an answer. If your diet is making you feel so rough and tired, that’s not an answer either. Your body needs appropriate nutrition. We have the drugs to help you eat properly if you need them. Did you know before the discovery of insulin, some people with Type 1 could go on for months or even a year or more? Yes, they were ‘controlling their blood sugars’ - they did this by starving themselves. We have absolutely no need to do that now.
Forgive my presumption, but I sense reluctance to address this particular issue because it’s something you don’t want to let go of. As someone who has let go of a similar problem, with hindsight I can tell you that the improvement in my life is massive. It’s like clinging onto a life-raft when you could let go and be picked up by a rescue ship. Yes, it’s hard to let go, and it can be scary, but once you’re on the rescue boat all of that will be forgotten. Take that leap of faith and reach out for the rescue boat. xx
