I get very bad panic attacks when I’m laying down in bed at night. My chest tightens up and it’s hard to breathe. I get very hot and my head feels so much pressure. I used to do breathing techniques to ease it but those don’t seem to be helping anymore. It seems so much worse during this last trimester. I have to sit up in bed and take deeps breaths in order to feel like I’m breathing normal again. 😕
