I took xanax and drank 3 bottles of wine yesterday
What were you thinking about before taking the xanax and drinking the wine?
I was thinking I wanna end my misery
Ending your life isn't the option. It sounds like you are going through a rough time, have you considered talking to someone about it?
I don't want to talk to counsellor anymore, they never can help me. I just don't see the point in living. I feel sad all the time.
Taking drugs and alcohol can have very dangerous side effects. It's always best to consult with a doctor before mixing them. I know it can be frustrating when it feels like treatment isn't helping, but these things can take time. Try to be patient, and it's good to talk with your therapist if you feel things aren't improving. They will work with you to help you get better!
