Nervous about starting Elvanse - advice?

Hey so after some wait I finally got my first prescription of Elvanse, and I decided to start tomorrow, I’ll be on 30mg for 2 weeks then 50mg for another 2 weeks before a review to figure out what to do next.

I am excited but also terrified - all my readings are fine (BP/ HR), I’m physically active/fit, no history of any medical issues, no allergies, literally nothing to really worry about, however I am always anxious around taking new medication. It always gets into my head that I’ll be part of the unlucky statistics with the worst side effects possible, I literally don’t even like taking the standard painkillers “just in case”. It’s not even the side effects like insomnia, headaches, jitters etc that concern me, somehow I’m scared I’ll end up with a cardiac event and die 🤣 (ridiculous but it’s anxiety)

My health anxiety used to be so much worse but it calmed down when my life overall started improving and my anxiety went into some kind of remission, but there’s still some underlying and I’m scared I’ll get a bad panic attack & then misread that as bad side effects from the meds which in turn will make me more reluctant to take them.

I just want some reassurance or advice I guess?

I’m already planning on having protein-rich meals, including breakfast, better sleep hygiene, etc. just curious about what to really expect and how to manage the anxiety before / during, and any positive experiences people had with it, thank you!
