Did I ruin my body by losing weight too quickly?

Weight loss regiment is the same since my last post

Essentially, for the first time in my life I’m talking to a girl(via instagram). I won't bore you with the details as there is not much here at the moment, but that whole exchange has made me think about how I'm basically leading any and all women on by not mentioning what my body looks like without clothes.

Apart from my face, forearms and legs, my entire body is covered in stretch marks, like it genuinely looks awful. I'm actually digusted by myself, and it doesn't help that I'm pretty sure I've started to bald, as my other family members which are, started around this time too(I'm 20). I'm going to see a dermatologist this summer to see if I can at least fight this, but it's just so frustrating. Every time I start to feel like I've gone forwards, I realize how much my childhood and genetics have set me back.

And now for what made me wright this post: from what I've read online, losing weight too quickly can make stretch marks appear even more visable, and at this point I just feel defeated as I've lost 45kg(99lbs) in 9 months, which from what I've gathered is pretty fast.

When it comes to "filling in" my loose skin, I've tried going to the gym consistently for months, hitting my protein, training to failure, resting, but I've made close to no progress. I haven't gotten stronger at all and there isn't a single muscle group that I'd say looks better.

It genuinely feels like theres no hope atp and I just have to accept the fact that I'll never look good without a shirt on.

Please don't wright any "omg you're doing so well!!!!" comments as I do not care if I'm "doing" well or "better" than before, those measurements have stopped meaning anything to me. I only care what I look like compared to the average person.
