There is not much you can do about your mother. Indeed, it is supposed to be the other way around. It sounds like she tried to help and maybe feels bad about herself that she couldn’t help more. Maybe she feels a bit like a failure and is putting that on you. Stuttering runs in families. Did someone in her family stutter? She might be reliving that burden and feeling responsible. You are going to have to move on. Tell her that you are the one suffering from the stutter, not her, and that if she can’t support or help you anymore then please be quiet about it. It’s bad enough for you as it is. Living with a stutter is tough. You’ve tried some therapies and you should continue until you find one that works for you. That is very individual. I used Hollins / HCRI in Virginia and liked them, but some others didn’t. It wasn’t perfect, but it gave me tools to stop that feeling of helplessness. You also will need psychological counseling as stuttering really does a number on your self image. I like Cognitive Behavioral Therapy because it is very focused and practical. Make sure you work on your self image. Stuttering really does a number on your head and makes relationships hard. This group can support you and there may be others in your area. Keep trying. Stuttering certainly gives you a unique perspective on life. I wish I didn’t have it but I do. It’s our cross to bear. I worked twice as hard as others to succeed because of it, and I did. Verbal communication is important in any job, so you’ll have to work harder at other aspects of your job, including writing. Keep reaching out to this group as you need to.
