Latent TB medications

Hi, looking for any advice/encouragement!

I just took a liver test this morning before I start my medication. I am a 26m in NYC, and was really surprised when I found out about my latent TB. I am otherwise pretty healthy and active.

I am mostly nervous about all the uncertainties with treating this and I'd appreciate any tips, recommendations, or thoughts in general. I was recommended either the 12 week Priftin and Isoniazid combo taken weekly or 4mo Rifampicin taken daily. I am not sure what to choose, my dr said that most people choose the 12 week to be done quicker but if I left it completely up to him, he'd choose the 4mo since taking a single drug is simpler to fix in case anything goes wrong.

From reading online (probably a huge mistake but here we are) I am getting really stressed about the idea of being constantly sick and having any complications. I could really use some help!
