Kia Ora bro.
Welcome
I get tingly hands & feet too - because my circulation isnt very good.
I dont know your employment circumstances, nor have I lived in NZ for a while, however when I was there if you earned under a certain amount you were eligible for a Community Services card, which entitled you to cheap/free doctor visits, you just have to call around and see which clinics accept the cards.
For years I was petrified of taking the antidepressants I was prescribed - I never filled the prescriptions. Last year things got really bad and I started taking them. Aside from giving up drinking its one of the best things ive done. It was what I needed at the time. Ive been off them for 2 weeks now and am doing fine, no withdrawals at all.
In NZ and Australia ive had to shop around for good general practitioners....
