I Quit Paxil Maybe 4 Weeks Ago. Now I'm Panicky,

I quit Paxil maybe 4 weeks ago. Now I'm panicky, having heart palpitations again, and coughing a lot. Should I get back on Paxil? Will this ever end? I don't wanna be dependent on pills but constantly thinking I'm going to die is hard. Paxil makes me gain weight and I don't like that, makes me not care about stuff, but it keeps me from worrying. I was on it for a year this last time.
