Merry Christmas & I feel like crap

Here's hoping for a Merry Christmas for all....in the meantime I feel like crap. Why you ask? Well, I've decided to chalk it up to these dag-nabit bc pills. They make me feel bad, ill, sick, not sure how else to explain it. I never had a problem with the bc pills I took many years ago as a teen and into my 20's. These are a different brand, so I am not sure if it's due to the brand or if it has to due with my age and hormonal makeup at this point in my life.
