hi,
i also have severe anxiety and panic attacks and my boyfriend doesn't really know what it is like. it's difficult to try to explain to someone who hasn't really been there themselves, but i have tried to explain to him what is happening inside. sometimes he really tries to get it and he is supportive, but other times he also gets frustrated.
i don't think that your boyfriend intends to get mad at you, i think that it is just very frustrating for him because he is helpless and doesn't understand. i hope he doesn't think it's an act -- i am sure he sees what you go through and understands it isn't an act.
i am sorry that your mother is unsupportive. it might be difficult for her to be if her friend committed suicide as a result of anxiety medication. all psych meds carry that risk and normally it says that in the medication description, and they all affect different people differently. i don't really know what to say about that
i wish you all the best with this and am sorry to hear of your struggles.
take care of yourself,
rebecca
