you have all the symptoms of a stroke...how old are you? I am going through same condition and had a stroke in October
I think what you may be experiencing is the after effects of the stroke.
My father had a stroke 4 months ago. He lost his ability to swallow, walk, and talk. Since then he has improved a greatly but he defintiely is not the same person that he was. He worked as a mailman but has not been able to work since because he gets fatigued easily, has numbness in his face and sometimes legs, vision in one eye gets blurry from time to time and etc.
What I learned from my father having a stroke is that recovery takes time. Life has changed dramatically for him as well. The first few months were rough, my dad being such a stubborn man, he wanted to do things he used to do but couldn't. He had to step back and take things one day at a time. He does hope to get back to work, but it probably won't be for a while.
My heart goes out to you and I hope you find your answers soon.
