Struggling to keep positive.

I’ve struggled with heartburn my entire pregnancy. In month four - I went into the emergency room & they put me on Pantaprozal because I had begun to develop and ulcer in my esophagus. I’m now 38 weeks and 4 days and I woke up at 3 this morning, with terrible heartburn. I’ve been fortunate so far to keep everything down, but my nausea is so bad. I’m light headed - and have next to no appetite. I’ve been in bed all day - and I’m really struggling to keep positive right now. I want to meet my baby - but I’ve been so sick throughout. I’m scared I won’t be excited when he is born. Plus I just feel awful.
