Anyone else feels like life is so unfair?

I used to have long ass long hair. It was never thick or super healthy but it still looked nice and I was able to style it well. Now I'm not gonna be so ambitious to say that I wish I had my old hair at this point but man I wish I could at least have normal hair with no bald spots. I was never super fixated on my hair but now I am and there's nothing I can do about it. It changed my entire life and I know it's toxic and I hate I can't help it. I'm too anxious to go outside because I know it's super visible, I often skip class because the idea of my hair loss being noticed (which it is and I can't gaslight myself anymore) just ruins my day. I'm too broke to get a wig and wearing hats is a no-no at my uni so there are no alternatives either. I just keep asking myself why me man like there are so many people who can live their lives carelessly not even considering the possibility of hair loss while my entire life revolves around it. It's just my luck to start losing my hair in my early twenties, like give it 5 more years and I wouldn't be as upset but like whyyyy meeee. I got an appointment with a private derm that will likely murder my wallet but I'm hoping someone will actually give me proper answers instead of \*uhhhh it's probably cause of low iron\* & being constantly dismissed but even then I'm not sure if I will be able to get proper treatment. And if I do it will take forever for my hair to get better (if it ever does) and I will miss out on my uni experience and feeling like a normal student. I hate it so much.
