Hi ladies. Please read this and respond. I had misscarriage in dec 2018 and had a baby in dec 2019. Am ftm. I don't know why i was being very emotional n getting angry very easily for no reason, yelling at people and over thinking. I wasn't like this in the past i mean before misscarriage. Sometimes i can control all my emotions. When i look back, am a different person n now am different. Am worried what if iam like this??????????? Are these all because if hormones?Pls lovely ladies any suggestions or tips that you could give me to change myself? Thanks in advance.
