Anyone have this feeling?????

Hey everyone...Must say I had a few good days there where I felt like I was normal. No heartburn, mild anxiety, just felt OK. About 5 days ago @ night I can't seem to relax. My heart is opunding fast and kind of hard. When I close my eyes and try to sleep I feel like my body is pulsing along with my heartbeat. Weird. And when I think I am almost asleep I get this jolt that wakes me up. That was a few days leading to my period, which started 3 days early. Needless to say I have been feeling extremely crappy this last week. Feels like a major setback. I just hope it is due to my period. I had that pulsing feeling again last night, along with what I think is severe hearburn.it wasn't painful, so I just dealt with it. If it had been, I would of for sure went to the ER. I am 3 1/2 months post and should be getting better. Maybe I am having that 4 month crash a little early.
