Which is the safest anxiety medicine?

I am having a hard time in the morning and at night with anxiety. I am a determined person. I don't set around having pity parties. I just hate having this nervous doom and gloom feeling. I work full time and am busy the other days. I just cannot shake this. I am not a pill popper either. Is there a medication to help me through this. Is Welbutrin or xanax safe?
