Thanks for using healthcare magic.
I have gone through your available history.
Do you have any symptoms of depression like sadness of mood, disinterest at work or irritability or disturbed sleep etc?? If yes, you should consult psychiatrist
for evaluation and depression.
If the answer is no, I do not feel any requirement of anti depressant
Withdrawal headache can be tackled with simple analgesic drugs like paracetamol
or diclofenac sodium or naproxen sodium.
You should consult dentist
for getting gel that helps in restricted mouth opening.
