How can I lose weight??

So I’ve struggled with ED in the past, and SH, my mental health is really bad when it comes to losing weight. I make all these plans, I’ve meal prepped things I wanna start eating and I’ve also gotten a gym membership but I feel so hopeless.

Tonight I’m really feeling bad in my own body and I hate it, I look down at myself and I hate what I see, I’m also an asthmatic and have a hard time just going and going and going at the gym because of it.

I also can’t do too much at once because I have some heart issues from when I was younger, I want to be able to lose weight and gain more confidence but I have no idea where to start and I feel so overwhelmed.

I feel like I can’t do it, I don’t really have a support system and I try to support myself and be engaged in it but some nights it’s really hard. I’m 4 years clean from SH and my ED but when it comes to me wanting to lose weight that’s the first thing that comes to my mind, I know it’s not okay though so I don’t start those habits again bc I know what happened last time.

I really just need advice if any of you have some, I need a place to start that I can maintain and I need something to feel accomplished.

Any beginner tips on meal prep? Things to eat? Or starting things at the gym?
