Welcome here! You do NOT sound stupid. I'm in that same boat. I've been bingeing and purging for the better part of 3 years. I have those same feelings. Striking a happy medium is so hard for us. Eat to little and I feel I'm restricting and eventually the dam breaks lose and if I eat too much I feel guilty and binge/purge. It's the perfectionist inside us.
The thing I'm in the process of learning is trust. My physical body knows when it's hunrgy and will tell me and going into the emotional issues when I'm not. Currently I am a raw nerve:-). Withdrawl from a tried and true (bad) habit is painful, no way around it.
A couple things I've learned is you can't lose the weight b/ping and then when you get there decide to learn the good eating habits to maintain. As they say the process is just as important as the end product. OA has really helped. Online or facetoface meetings. Connection is really important. Start reading all you can about it. And keep a journal. Take that internal struggle outside yourself. You can't do it alone. Forgive yourself for the mistakes that you make and move on. I'm learning that one bad meal will not destroy me. I ate a huge dinner last night. Salad, bread, eggplant parm, a couple of drinks at a party. I wanted to go nto the bathroom and get rid of it but i stayed where i was and enjoyed the rest of the party. Came home, slept and at 10ish my stomach growled for food. My ed lies to me all the time, there is no truth or comfort in it.
Hope this helps you:-). Didn't mean to ramble

. You are NOT alone. Take care.
