Depression/Weightloss Troubles

I know I haven't been on the site in so long cause I've been distracted with other things puzzles and worries as well as depression among them. Well as it turns out once again my Depression has come back in major waves and along with this I've been having weight loss problems.

For explanation, I have a major knee problem and in the near future I would need a replacement but in order to get in done earlier rather than later I would need to lose a certain amount of weight. But as anything goes, I have cut out a lot of things I know would help including skipping meals and cutting back on certain things. I have yet to see any progress from a horrible scale even though it is relatively new.

But every time I do start a new diet or try new ways of eating my depression always follows and it's only to have seem to gotten worse this time beyond where my usual distractions that help don't .

Now I'm not paranoid about eating but I have gotten scared of gaining even the littlest of anything. I have a few people I can chat with but it only helps for a short time and a few times I basically broke down with the worse of emotions. I'm asking for any sort of advice beyond diet drinks, or medication because I have been following and doing the best I can at the moment.

I hope you all have a blessed week and I pray whomever gives advice that it works .

Thank you
