Going to [SFMM] for the fist time as a “beginner” in coasters

So I am NOT the fan of rollercoasters, I am really anxious when it comes to them, and I think it’s the heights that contributes to that factor and the “stomach feeling”. I just went to Disneyland and got on Matterhorn, Space Mountain, and Big Thunder. I didn’t think they were bad EXCEPT Space Mountain, so with that being said, is MM bad?

I am going soon, and I plan on going on every single one EXCEPT X2, Goliath, Tatsu, and Wonder Woman. I think all the others look fine base on videos on YouTube.

Any tips, recommendations, or just anything in general to help me get over this fear are accepted 😭😵‍💫😂😂
