Skwirl, when I turned on my computer and read your post, I was like wth!? What has happened to put you in this horrible state? Have I missed something here? Please try to get hold of yourself for your sake or you may end up in ER! I mean panic attacks themselves may be "harmless", but eventually the stress can cause some serious medical conditions. I think you probably know this though.
If this is because of your mother then maybe it's time you rethink your place in all of this. I mean nothing, nothing is worth your risking your health. I am also concerned if you are trying to get pregnant because taking serious medication like that cannot be good...nor can the stress. Are you in therapy? Is that something you would consider?
I wish you well and please try to remove yourself (somehow) emotionally from whatever the situation is that's causing this stress on you. I know it's not so easily done, but this is exactly what I had to do because I decided my health was a bit more important!
