Why do you feel so weak all the time?

Answer 1

You may feel weak all the time because you are exhausted,tired and need more sleep. Or you are not getting enough or the right nutrients your body needs to stay active.

Maybe you are malnourished or your parents are too poor.... (what kind of question is this???)

Feeling tired and weak is one of the primary symptoms of mononucleosis. It's also one of the primary symptoms of lupus. It's also one of the primary symptoms of depression.

Whatever the problem is, the only person who can really help you is a doctor and/or psychiatrist/psychologist.
