Thank you for your reply, I do take medication to try and help with the voices, but nothing has helped yet. The voices are nasty they tell me I'm useless and worthless, it wears me down, they say I don't deserve anything, it's horrible, and it's all the time.
It's been my experience that medication doesn't silence my voice completely but it does take all the stress out of hearing him.
Ultimately mine knows how sad and pathetic he is so doesn't try and bring me down like yours does. He does however whine about me not talking to him for the past three years and 125 days (same amount of time I've been on medication) and begs to come off medication but I just can't handle his volume and speed without them so that's a big no for me.
Medication does hurt voices in many ways so they will either become quieter and submissive or more aggressive which I'm sorry to hear yours has become the latter.
When they really start to get you down you could try listening to some uplifting music or repeat a positive mantra about yourself in your mind. Something along the lines of "I am worthy, I am loved, I deserve nothing but good things", maybe not quite like that but you get my point, think of positive things and your voices might get a little weaker from doing it once they know you're stronger than they are.
