Oof. A few things.
1. I felt "I'm tired of being tired" in the very core of my being. I'm sorry you feel that, but know you aren't alone.
2. I agree with everyone else, shakes can be great. If you're like me tho, I CANNOT get beyond the taste. They are usually so nasty or they are full of things I can't have (gluten, soy, dairy 😕). I try to make things in batches - a ton of rice, a dozen boiled eggs, a bunch of cookie dough (bc fresh baked cookies are always better). Then, all you have to do is eat it. That said...
3. Sometimes even if the food is right in front of you, you still don't have the energy to eat it. That's tough. It reminds me of this study I read about mice who had a severe lack of dopamine. They became so unmotivated that they wouldn't eat even if the food was right in front of them and they would literally starve to death... with an abundance of food around them. They would chew and swallow if the food was physically put into their mouth, but otherwise wouldn't eat. I'm not really sure what do to with that information, tbh, but maybe it will make you feel better as it made me feel better to think that it isn't that I'm "broken" but that there's probably a despirate deficit of dopamine in my brain making me how I am. I have 100% laid in bed, hungry, with a bowl of food in my hand that my boyfriend made for me, without the motivation to move the fork to my mouth. It's tough.
4. To get myself to eat, I sometimes will "eat with my brain and not with my stomach." Meaning, I pick foods I know are good for me and I don't pay much attention to if I WANT to eat them or not - especially when I don't WANT to eat anything. Pick a veggie, a protein, a grain, maybe some fruit, dairy if it agrees with you, and something sweet. Then just eat a little of each until you can't eat anymore. If that's a bite of each, then it's a bite of each and that's okay. Just do what you can, and leave it available for when you are able to come back to it.
5. Be patient. If you haven't eaten much of anything in so long, your stomach will have shrunk. Don't beat yourself up about not eating more than __ amount because you might not physically be able to! It is good to slowly stretch it back out, but that can be a nice, slow, gentle process where you gradually eat a little more and a little more. It is uncomfortable, but important to do - just not the first priority.
Be kind and loving to yourself. You are fighting a difficult battle and it's a long game, not a sprint. I'm proud of you for trying again and again ❤
