That is really, really tough about your mom. I assume you're a teenager or young enough to be living/dependent on your parents. A good speech therapist SHOULD be talking directly to your parents/mom about their attitude and the way they interact with you about it (SLPs will often say that working with clients is easy, it's working with the parents that is much harder!). I would be very, very open with your speech therapist about the home situation, as that really can create a lot of issues that are completely unnecessary. The therapist can help you navigate that and be your advocate a little bit to try and create some change. That's a really tough situation, and I'm very sorry to hear it. I have a couple of adults, now married and working and off on their own for years, and their parents still "blame" the kid for stuttering, say it's all in their head, etc. It's very painful and hurtful and there is not a lot you can do to change someone else. That's why finding an outside support group (NSA, StutterSocial, FRIENDS, etc.) is so vital.
