Just wondering what your daily symptoms look like

Good Morning everyone. I am a 38/f and I am still going down the rabbit hole of testing and hopefully will arrive at a diagnosis soon. I have had bloodwork, MRIs and EMGs, all of which came back normal. However, I feel everything but normal, I have been struggling since October. I was diagnosed in about November with a B12 deficiency and started injections. I thought I would go back to normal once my B12 was brought back to a normal level, but it didn't. It did improve my symptoms as far as muscle twitches are concerned. This has ruined my life as I know it, I can't even grocery shop, play with my kids, go on walks, etc. Every day my legs are cramped up, tight (feels like every day is leg day at the gym), my left hand is consistently numb as well as my right leg from mid calf down and my left lower lip. I get random twitches in my muscles. The brain fog is awful, I can't remember things very well and i lose my words when I am telling someone something.... I feel dumb. Some days are better than others, but never great. I also gets bouts of tachycardia and feel like I could pass out. What is everyone's daily symptoms?
