Hey, I'm trying to maintain/lose very slowly too. I don't have any advice or anything but it sucks and is scary and hard.

I went from eating at a 1000cal/day deficit to a 500cal/day deficit for a month or so once I hit my goal weight (bmi in the mid 15s), and now I've been trying to keep my deficit at or less than 500cal/day which is scary. I don't want to lose too too much more too quickly because I'm worried my doctor will make me change the medicine I'm taking for my mental health (which besides food stuff is doing way better).

Instead of having weight loss goals I have maintenance goals now. I use this app called happy scale and my current goal is to keep my weight below my goal weight for all of March (doesn't matter how far under, just under). My next goal is to keep my "average" weight under my goal weight for all of April. I also have nutritional goals, so making sure I hit my target for protein.

Idk I identify with what you're saying about feeling more restricted by eating more and suddenly not having a big budget of calories to spend on whatever you want. I don't really have any good solutions :/ The two things I've tried are planning and prepping all of my meals in advance so when I wake up everything is already logged and in tupperwares and just needs to be thrown in the microwave and eaten with no thought or stress on my part in the moment. The other thing I've tried is intermittent fasting, where you basically don't eat all day (I have lots of water and maybe a small snack) and save all your calories for dinner. At least for me I don't have that restricted feeling because then I have a huge budget for whatever I want (the risk though is that I get into disordered thinking like I haven't eaten anything today and I'm not even hungry! I won't eat anything tonight! I'll be so thin! But then I have to remind myself that that's not the goal, I want to maintain, I need to eat protein, etc).

Idk, it sucks and is hard :/ you're definitely not alone
