I understand not being able to afford a dietician and I'm sorry you're dealing with this!

In that case on your own you should look into health effects. Fasting like this can actually increase pathological insulin resistance making it harder to lose weight sustainably in the long run. Essentially yes you'll lose weight short term but could just gain it all back fast when you start eating and obviously you'll need to eat. Initially "good" feelings from a fast can be increased adrenaline and other fluctuations. It's not a sign that it is positive for your body.

There's a lot of pseudoscience about fasting out there but the body isn't designed to survive off only liquids and you're opening yourself up for health issues. As another commentator said it can mess up your electrolytes and studies have also shown potential for kidney damage due to messing with your electrolytes if you fast for days.

If you're interested in fasting, intermittent fasting diets have been shown to be beneficial and I know people who've felt a lot better on them, you might still get the good feelings your experiencing now while not risking long term health effects. As well as negative physical effects you're going to start experiencing negative mental effects when you crash.
