How to deal with having mean/bad mom?

Your mom sounds like the character who portrays Roseanne Barr. She may seem mean to you because your personalities are so different. Most likely, you are sensitive and she is brash, but not a mean or bad mom. Just loud sometimes. I think you should let her know when she embarres you and how it makes you feel. Just to show how sweet you can be, do something special for your mom once a week, that says I love and appreciate you. Your mom maybe feeling unappreciated.
