Can my GP renew my old antidepressants prescription?

I was diagnosed with depression when I was 17 & prescribed medication, however I stopped taking them not long after bc I was scared I would become dependant on them.

I'm now 21 & feel as tho my mental is suffering horribly, the last few months especially, and I really think I should go back on them.

Will I be able to go to my GP & have them renew my prescription or will I have to go through a psychiatrist?
