What can i do when my loved one is suffering from the side effects of meth?

i barely found out that my loved one has been taking meth for many years. his last time was 2 months ago. he says he doesn’t want to take it anymore because the thought of it just makes him sick to his stomach. i believe he is suffering from the side effects of it. he has been suffering from panic attacks and depression over the last few weeks. i have never seen him like this before and i dont know how to help him. he wants one on one help. i suggested that he talks to someone professionally but i don’t know whether he should see a counselor, phychologist, clinical phychologist or phychiatrist?
