worry please do not feel guilty at not enjoying pregnancy. Some ladies love it, some hate it. I hated my first pregnancy, my second, I disliked but Im enjoying this one, I think because everything's different this time and I know it's my last time doing it. Remember you're well over quarter of the way there and after these horrid 40 weeks, you've got a beautiful child to love for the rest of your life.
I suffer with panic attacks too so I feel your pain, I am currently un medicated as my tabs can affect baby, thankfully, I think the pregnancy hormones are levelling me out a bit, and touch wood, no panic attacks. I know it's tough but I think you're going to have to get on that phone and make a pain in the arse of yourself, don't let them ignore you or fob you off, keep on until they give you the treatment you need.
