Am I valid?

I'm a trans girl. I'm 16. I struggle with my health. I have vision issues. I feel like It's impossible for me to be happy sometimes. Luckily I'm kinda cute (a little bit) . But I do have a masculine body (I have pretty broad shouders) I was wondering if any other trans girls, or trans guys, or trans people in general who struggle with their health like I do. I became rlly addicted to weed to cope because my parents are against my transition. It made my health issues a little worse. I quit though. I've been sober for 2 weeks now. But I was wondering if I'm valid? Sometimes I don't feel the best because my illness flares up and it scares me and makes me feel like I'll never be able to be who I wanna be. I'm trying to lead a healthier life though. I'm planning on eating healthier.

Am I valid though? Is it okay if I take stuff slow and try to improve? I know seeking validation isn't always good but I feel like I need it.
