Anxious about diagnosis

So two days ago, I had both an asthma and panic attack that landed me in the hospital. They intubated me and got me back to normal thankfully. The doctor diagnosed me with asthma and told me I’ll need an inhaler. I know that it’s not horrible and asthma is common but I’m still nervous. Idk what to do with this information or change and I’m scared I’ll get messed up all over again.
