M/20 need to lose 250+lbs

Hi everyone, I'm kinda new to Reddit and this is my first post on here, but I was hoping people here might be able to help me. So I've recently turned 20 years old, I'm 5ft7, and I weigh approx. 430lbs. I first started to put on weight in 2020 during Covid and since then I've gotten increasingly heavier, the past year or so has been the worst as I've gained over 100lbs. I've reached a point where I can't ignore how severe my weight problem is but despite my best efforts in recent months I'm really struggling to make any kind of progress or changes that'll help me to lose weight. I feel very dependent on eating almost constantly, and I'm really struggling to find exercise or even basic physical activities that I can manage to do to help me lose weight. If anyone has any support or advice they can give me to help me get started I'd be so grateful because every day I'm struggling more and more with my body
