First of all, don't you worry because I think issues with depression and hopelessness are so much more common than we think, especially amongst people who want to lose weight. There's the emotional side which is quite heavy because of how people see obesity and weight gain, but also a physical side - you do actually release less endorphins and feel more sluggish, which just adds to everything else. I mean, we even have a forum just for it:

But it's funny looking back on my own trajectory now, that when I had en eating disorder and would hate fat with every fiber of my being, I could never do anything to truly help myself. I thought my motivation would never allow me to find a true balance, that I could either overeat or not eat at all, and that I was just not capable of finding that middle ground. But over many years of building some confidence and making significant progress in the long run, I've started noticing that I do so much more for myself when I feel good? And I know it sounds obvious, but it's not just a "getting better gradually" thing - I'll notice that I'll eat well if that day I feel refreshed and have my tea and put on my creams and exercise and whatnot, but the one day I choose to sit in my PJs I'll already be so much more prone to going for junk food and overeating. It's so funny to me just how psychological this whole journey is, and the more I go into it, the more I notice it really does have to be mind over matter, because how you feel a defining influence on what you end up doing.
Do try to think of it as progress anyways, though! Even if you gained weight, you're still coming back with more knowledge on how you're supposed to lose weight. There's a whole batch of research and adaptation that you don't have to go through again, and even though we forget it, trying to get into a healthy life with no clue on what the best paths are can be the hardest part. So you're coming back into it, but wiser and therefore more effective in your journey, if you stick to what you know!
While I'm not from an abusive household, I don't have much support, and what I have learned (and hopefully will help, even if in the slightest) is that you're the one who's doing your research, you're the one who's investing the time to figure out what works best for your body and your taste and your schedule, so if anyone's going to really know what's best for you (from a very objective standpoint) it's you. So if you do receive a lot of critique, what helps me is to be totally objective and realize my family doesn't really know anything about health, and I'm no expert but I've already gained a knowledge base to know that what I'm doing really is good for me and it's none of their business to tell me otherwise without knowing what they're talking about. It seems harsh, but family members will often be very subjective and try to put you down for reasons as trivial as jealousy or discomfort with changes around the house, so it's best to not give those comments undeserved value.
Wish you the best of luck!
