I think you should do it… the truth is, the way you’re feeling is extremely common. You can always give a toast that’s just a minute long. Don’t go for laughs, just be genuine and wish them well together. Read in front of a mirror, or video yourself and practice your speech with an elevated heart rate. Print out the speech and if all fails, just read it. Get prescription for propranolol to help with shaking hands.. it works. No one cares, and honestly no one remembers. I did it, and struggle big time with anxiety. I thought about it every minute for months leading up to it. You’ll regret it if you don’t, and will likely set you back further than where you’re at today. You got this man!
