what are the symptoms of missing someone?
It's definitely possible. Missing someone you care about can actually be stressful and stress can cause many physical symptoms including headaches, upset stomachs, muscle tension, etc. Prolonged stress can cause depression which can involves numerous physical symptoms such as fatigue, sleeplessness, and muscle aches and pains among other symptoms. i wouldn't say its normal, but it's not unheard of. If you love some one that much, you can feel physical symptoms when they aren't around.
