Anyone else?

I found out I have a disease very similar to vertigo. I wouldn't have found out of I didn't have a spell at school. Being in full time college and already having other kids isn't an,easy obstacle. In now 32 weeks and,1 day. My Dr is highly concerned about my weight. I've not ever been over 130 even with my other two pregnancies. I'm now gain 10 to 15 lbs a week. He has had blood work drawn to check my thyroid. I'm depressed all the time cause I'm almost 130 lbs. And the weight is coming in way to fast. I'm constantly in pain. I'm constantly sick. As the myth says the third trimester is supose to be a womans best but this has turned out to be my worst.
