I've Been Feeling Shaky Lately, Just Not Feeling Like Myself.

I've been feeling shaky lately, just not feeling like myself. Left ear has been bothering me. I have a lot going on in my life. I have a tooth that is bothering me that I need to get pulled. My chest bothers me sometimes. I got an EKG done it came out fine. I've lost some weight. I don't eat the best either. My stomach had been bothering me too. I feel kinda tired to. I don't know what to do
