Arfid, addiction to sugar, caffeine and salt

I'm starting to lose weight again and I've dropped below my healthy BMI at my height of 5ft 10in. For the past month I've been really sick with flu like symptoms and chest congestion, so it's reduced my appetite for food. Not to mention that since I started working again I started to rely on sugary caffeinated drinks to help me destress. However, I've really been over doing it with the caffeine, to the point that I stay up late and start having irritable rage attacks. I've been really stressed lately, and I've been eating little to nothing, and I hate losing weight. I used to be curvy and now I can't even look at myself in the mirror anymore. I drink caffeine every day. I mostly crave foods that are high in sodium, caffeine and sugar. I honestly don't know how to quit my caffeine addiction without cravings and withdrawal. I just don't know what to do at this point. With work getting in the way and taking up valuable time for me to be eating, it feels like it encourages me to eat less and to rely on tea and soda for most of the time. I'm underweight, constantly dehydrated and I feel like I'm falling apart.

Sorry you're going through this

Do you have a nutritionist? They may be able to help you figure out a plan to start decreasing the caffeine and sugar. It may take some time depending on how much you take in on average. They're usually good at coming up with plans for making alterations to diet with small steps at a time so it's more manageable

I thought of originally taking a caffeine reducing supplement, but I honestly question how safe it is. As for the dietitian, I could once again go back, I just need a referral to one. Another thing I didn't mention is that I'm trying to reduce meat intake to save the environment, and I wonder if it's drastic to my body and needs.
