My sister tells me I take things wrong a lot and tend to snap at people. I guess I do but when i hurt all the time it's hard to be sweet.

Don't feel stupid I think with a flare we are in so much pain that the sarcasm is just not at a right time so our brains choose not to hear it. When I'm in pain sarcasm is the last thing I want to hear. I hope this help

For my in laws and hisband for 25 years sarcasm is a way of life. Hard for me to understand. Now that I have this fibro I am more sensitive. I try to stay away from them except my husband of course. I can only tolerate it for so long then I need months to be able to be around it again. My boys are used to that sarcasm but I notice my daughter hates it so she also stays away from them. I think fibro makes us more sensitive or maybe being sensitive brings on fibro?

i always tell people ,look i am hurting bad today so if i snap at you i don't mean it ! so i do give people fair warnings ahead of time !

I am not sure if this is due to Fibro but, I do know if you do not understand the sarcasm being said to you, maybe you need to keep that person out of your life, or at least tell them you do not like it. If sarcasm is used toward you because of the Fibro, I would just blow them off. I know it is easier said than done, but no one deserves to be treated with disrespect.
