<human>: Can you give me the gist of the text in a nutshell?

My sister is getting married this Friday and I am her maid of honor. The only problem is that I have a crippling public speaking phobia and severe generalized anxiety disorder. My brain just shuts down and my body goes into serious fight or flight mode with nausea, trembling, face reddening, etc. I told my sister this a little while back and said that I regretfully couldn't give a speech at her wedding. She recently e-mailed me asking if there was any compromise and suggested my boyfriend give a speech for me but said that if not, it's ok because she doesn't want me to feel bad/uncomfortable. Both he and I think him giving a speech for me would be incredibly awkward/embarrassing/inappropriate for both of us and he feels uncomfortable doing it, but said he would if he needs to. So I guess my question is what should I do? Is it really abnormal/embarrassing for either me or my sister if I didn't give a maid of honor speech? Should I just have them skip over me and ignore the fact that I'm not giving a speech? Should I have my mom mention in her speech that I'm afraid of public speaking and that she's speaking for both of us (which she said she'd do)? Personally, I prefer to just skip over me and ignore it, but I'm also very afraid of how that will be perceived both for me and for my sister.

Any help would be much appreciated!
