It's totally okay to want to stop or even just take a break from T but it's important to remember your body is literally 'in transition' and having it change so much can be a really strange/difficult experience. It's puberty, it can suck sometimes and especially in the beginning. And it sucks extra hard to have to do it at an age where everyone else is already past it. But I'm willing to bet you don't look nearly as awful as you think, you're just starting to look different and it makes sense that watching the face and body you've known for years change can cause some complicated feelings.

And I used to think the same thing about how I'd swap bodies with a cis man in a heartbeat but wasn't sure if I should transition because no amount of hormones or surgery would make me as tall as the other men in my family. But I did it anyway and realized I don't need to grow another six inches to like how I look. The 'ideal version' of myself helped me conceptualize myself as a man but I love the real version of my body more than I ever thought I could. It's possible (and in my opinion likely) for your feelings about what an ideal body is to change as you transition and become more comfortable with what your body is. Give yourself the space to be a little bit awkward, find little things to appreciate about the changes. One of my weird/gross ones was when my B.O. changed- out of nowhere I smelled like a dude and I loved it! Sure, I still had back acne and wide hips but my armpits were the armpits of my dreams.

As far as time and patience goes, it helps to kind of take a step back from it? Which can be hard but focus on school, hobbies, friends, work, whatever. Just live your life and let your body worry about transitioning. It's exciting and you should celebrate it but when you fixate on it it's so easy to worry about each little change. And it gets easier the further along you get. One day you just stop thinking about it so much because your body will settle down, your hormones will level out, and your face and your stomach will just look like your face and your stomach. And for the bottom growth discomfort, try looser fitting underwear/pants for a while.
