BP or not, your are allowed to have opinions and moods. BP gets used as an excuse sometimes when they don't like what they're hearing. I too had some friends who used to do this and some did it in a way b/c they cared and others did it to be hurtful; those weren't my friends. It's natural for everyone to have changes in their mood; it's just to what degree and the fact we take medicine for it is of no consequence to them, is only beneficial hopefully.

Talking to true friends about it can be helpful and letting them know it bothers you when they bring it up but let them know what are truly signs to look for that might indicate you might be in trouble; the others, I try to ignore and keep my distance. I have learned to keep this information more to myself now because of it though and to only share it with those I am really close to.
