You are most certainly being mistreated and verbally/emotionally abused. Terms such as selfish, brat, irresponsible, etc, are character assassination terms, which is abusive. Turning the tables around on you and blaming YOU, when you try to tell them how you feel about their treatment of you, is abusive. Invalidating your feelings is abusive. So yes, you are being emotionally abused, and I am very sorry to hear it. As the poster above says, they are not a good support for you. Can you seek additional outside support on your own? I hope?

And yes, you have every right to be upset. Please don't internalize their characterizations of you -- those are their twisted words that hold no value or validity. Keep your head high and believe in yourself and your own reality of what is happening with you. (((((((Hugs))))))))
