Hang in there and try to not to lose sight of the gains you may see no matter how small! I went through the same and it is frustrating! If your stroke was anything like mine, believe it or not, you will get better! It just takes patience and work. Your speech will improve and you will find things become less difficult over time. I found I had to keep the number of things I focused on in rehab small, focus on just a few things, it was too overwhelming and depressing thinking about fixing the 1000 things I was struggling with as the result of my brain injury. Once I would get one task down, I would remove it from rehab list, chalk it up as another win, and add another task I was struggling with. I found it is all about repetition and you will get there! There were times when my progress stalled or seemed to go backward a little bit, but it would always pick up again in a few days. BTW, feel free to vent, not a bad thing, I know exactly what you are going through!
