I too am sorry that happened to you.
Heck yes you are capable of real feelings/emotions!!!!!
(I think all your feelings/emotions are "real" and deserving of validation and concern, actually. But I know what you mean & can relate to being blown off for "just having an episode or symptom")
And I also think it's your friend's problem--what the heck was going on with her and the way she was treating you probably didn't have anything really to do with you, she was upset and taking it out on you.
But that doesn't make it any easier to take, for you.
I hope you are feeling better by now.
