Looking for a text-only game, no discord or anything, just text

im 13, want to take after my mum and play d&d, but I don’t have any clue how to play, only simple stuff like “my character does this” and I roll a dice. I have adhd and autism, and I go by they/them, and my iPad guzzles power, so I may accidentally disconnect mid game, so I’m sorry if this disturbs the game, and I’m a bit of a slow learner on games, but I also want a more roleplay-focused game if possible, I will show character in the game (idk I think I can), so thanks, and it also must be free, as I’m more poor than a homeless person, and since I have school, on weekdays, est, I will be only able to play from before 8:40am to around 3:30-4pm, but on weekends, I can play for entire day, and on Friday nights entire night, due to me having all-nighters

Having all nighter so might or might not be asleep in about 4-5 hours

Going to sleep now

Awake :D

Still no one :/
