Am I overreacting?

Now that I'm pregnant I just think that everything I'm doing hurting or effecting the baby & the way it grows.. I keep missing meals & my bf smokes& i 2nd hand his smoke 😟, i smoked and drunk like the night before i found out i was pregnant & i had 3 hits of a capone today😩 im going to stop smoking of course, its just hard ...and my job I have Im constantly bending down & lifting things but not more than 20 lbs. .. I just wanna know if this can damage the baby & its ablities when he or she is born (im stoping all my bad habits tonight !)
