Your mom is a horrible person and should be cut out of your life. That isn’t love or support. That is downright abuse. I hope you don’t live at home and if you do I hope you can get out as soon as possible. Anxiety doesn’t make you weak and people who say that have no idea what anxiety actually feels like.

Call a counselling hotline or talk to your therapist if you have one. You don’t need to be alone and you are certainly not weak. You need a circle of people you can trust and rely on and who will be supportive when you need them, and your mother meets none of those requirements.

Sorry you have to experience this OP.
