Loose skin after weight loss

So, I need to lose about 120 pounds to be the "ideal" weight for my height. I've been fat my whole life. I know I'm going to have a LOT of extra skin afterwards. I hate being fat, I hate looking in the mirror and seeing how gross it looks. But I know that if I put in all this effort to lose this weight, and all I get out of it is ugly, saggy skin (no offense to anyone that has it!) I'm going to hate myself and the way I look even more. I've heard people say to think about it like "oh that shows all the progress I've made" but I know full well that isn't going to work for me. I've been picked on forever for being fat and ugly, and I know it sounds awful, but a huge part of why I want to lose weight is to feel good about how I look because I've lived my whole life hiding and hating my body. I want to be able to wear tank tops and strappy dresses and bikinis like these pretty skinny girls do... ain't no way I'm going to be doing that if I think I look like I could fly away with the wings on my arms, or the skin on my stomach hangs over the swimsuit bottoms. I know I'll be even more self conscious if I have too much saggy skin, to the point that I'm considering only losing a few pounds just to avoid it. Does anyone have any tips or comforting thoughts about this? I'm stressing way too much over this lol but I can't help it

I want to say THANK YOU so much for all the comments! I forgot about this post for a bit, and got on the app today to find this. Some comments actually made me cry. You are all such beautiful women and I love to see all the self love and support!! I'm taking this journey slow because I've had the issue of punishing myself with strict diets because I'll look in the mirror on a bad day and get angry with myself for letting it get this bad. I'm trying to focus on the goal instead of how hard the process is going to be, or why I allowed it to get to this point, etc. Hopefully later on I can come back to look at this post and be proud of progress I'll have made. Thank you again for all the love ❤
