Am so fatigued weak arms legs and tingling in foot?

Go see your doctor: You need a much more thorough examination & evaluation than can be offered online. Fatigue & weakness is multifactorial ie caused by many different things such as depression, anemia, hypothyroidism, kidney disease, etc. Tingling in foot suggests peripheral neuropathy due to diabetes, vitamin deficiency, or physical nerve damage. Weakness in arms & legs suggests spinal cord issue or poor fitness.
