Nervous for my Thailand trip next month

I have always wanted to go to Thailand and over the last year I have been planing my two week trip next month. Myself (28f) and my husband (29m) and his cousin and wife are coming with us. I have been so excited for our trip until recently. Going to Bangkok, Krabi and Chiang Mai.

I’m feeling super anxious about the trip, i dont know if im getting older and have more fear. I’m scared about getting food poisoning and a tsunami happening (I know those chances are so low).

Any advice will be grateful, or things to get me excited for the trip!
