Snowflake,

Around my cycle I do notice I have more symptoms. I haven't experienced exactly what you talked about but can very much relate to how you feel, I am more cardio sensitive so usually I get more palps etc. I believe as well as others here probably do that our hormones play a big part in anxiety feelings. Take care lots of great people here to shed some light. Btw I do get the shakey feeling it feels like I am shaking on the inside and it can travel all over my body. Hugs for a good day.
