For some they wish to recover and gain weight as quick as possible, they want to be healthy and happy and the person they were before the illness (or well a newer version of the old you!) They want the recovery progress to be quick. And then on the other side those just want to gain 1kg a month, then lose 0,5kg next month and repeat and want the recovery process to go slow, not to fast because then it might be "too much".
Either way you think I think you should let recovery take the time it takes. You don't need to rush recovery because mental recovery does take time, it's not just to eat. But you don't need to prolong the process either and take backward steps if yiu think you made too much progress or went forward too fast. Recovery can't be controlled precisely, you never know what happens, you just need to do your best everyday to fight your fears and focus on happiness and a healthy life. Trying to control recovery by speeding it up or slowing it down isn't a good idea just like with weight gain, let your body take care of that and don't try to speed the weight gain or slow it down to tiny amounts each month. Recovery is also about learning to let go of control and if you begin controlling recovery too much it can be much harder to actually recover as you get stuck in the recovery bubbled and never take that step to fully recovered.
Recovery is not a 6 week plan with steps on what to do when, it's about making changes and facing fears. It takes time and also if you need to gain weight, that takes time as well. So I don't like when people around the person who is struggling expect a person to be recovered in 8 weeks time. It most often takes longer than that even if alot can happen in 8 weeks.
Allow recovery to take the time it takes but keep motivated and keep pushing towards a healthier and happier you! ! Don't get stuck in the recovery bubble (where you are too scared to actually recover /fully recover )!!
Recovery is worth it and you need to remember that. You can always make changes to make things different but the first thing you have to do is to try!
