are these withdrawal symptoms?

Ive been a heavy smoker and drinker since I was 15. I am now 23 and about a month ago I quit smoking and drinking cold turkey. Just quit all of a sudden.
And since then ive been having severe anxiety and regular panic attacks. Been coughing soo much.. which is weird cause when I smoked I never had a cough. Also major migraines and headaches. Just feeling really ill in general.
Could these be withdrawal symptoms?

Definitely. In general, for any illness or disease other than a common cold or flu, you should always ask yourself what you did that is different from your normal just before you got sick or just before the new symptoms came on. You stopped smoking, and suddenly a bunch of symptoms shows up. Chances are... :)
