My Mom is Disappointed that I Stutter.

My Mom is Disappointed that I Stutter. I'm sorry, this may be all over the place and ramble but I'm just so emotional right now and I need to get this rant out. I am aware it is "poor me" and childish and I know I'll get comments about it and I'm prepared for them :) trolls will always come to Reddit. My mom told me a few months ago that she was disappointed in me that I stutter. I've tried to get it out of my head and get over it but things from my childhood and what's happened recently have brought it up again. I'm a 21 year old female so it hurts that she waited so long to tell me and that she acted like she supported me this whole time. She took me to stutter camps, special speech programs in the next province, speech therapy in elementary school and even got me a device for my ear a few years ago to help my stutter. Nothing has helped so far to my frustration and my mom has always held it over my head how much help she gave me but I didn't get better, that I didn't "use my tools". I did try for many years but I still stutter quite severely and have throughout my life. Still, she acted like she supported me by letting me cry on her and vent when people bullied me and was patient when I stutter until recently. Now she tells me to hurry up, gets upset I stutter and that I seek other ways to communicate with people. Texting/emailing, writing my food orders on a pad I carry around for waiters/waitresses, and avoiding making and receiving phone calls. For me, finding jobs is a nightmare, ordering food, making appointments, even making friends and talking to my family and boyfriend. Of course its a huge source of insecurity and it makes it worse when my mom does this. To add some details, my sister is fully fluent but my brother stutters as well, though not as bad as me. She always brings that up too, saying if my brother could learn to control it why can't I? This has grown some resentment but going to therapy has healed that and me and my siblings have a close bond. And yes, therapy didn't help either with getting more fluent. What can I say to my mom to make her stop saying these things or at least understand my side? I've tried to communicate with her multiple times about it but she just brings up how much help she gave me when I was younger and leaves it at that. Its frustrating and hurts my heart that my own mother feels this way towards me. I'm trying to look at the bright side and not be so negative but it's hard with this mindset and trauma. I am currently working on just letting it go with the help of therapy. Until then, turning to internet strangers for advice it is! :)
