Those that love us/are close to us sure do know the way to hurt us the most. I suggest you mother knows your inner turmoil and manages to voice your own fears about your mental illness. The fact that she can cause these emotions in you by saying those harmful words means that you may secretly believe them to be true. You have low self esteem and cannot defend yourself against her.
If would be a positive step for you to read books on self-esteem and/or seek psychotherapy for the same. Once you internalize that her comments are NOT true, you will be able to build a defense mechanism against her hurtful comments and ANYone's hurtful comments. Those of us with mental illness know how others can be hurtful because they don't understand what we are going through...and sometimes really don't care to learn.
I also agree that if your mother can't stop her tirades against you, you may want to seek some distance from her while you are getting stronger. You could seek some help first before trying to help someone understand what it is like to be you.
I can't afford psychotherapy, but I find reading books to be helpful.
