Can u buy depression pills or do u have to have a prescription?

There are certain vitamin supplements like magnesium, I believe, that are supposed to help with mental health, etc. I think it is much more wise to be assessed by a doctor, though. Especially if your depression is severe or crippling.

You need a prescription. Although there are some 'elements' and plant extracts that are supposed to help depression, there is no concrete evidence for them.
Recently there was a major study showing that most anti-depressives are worthless, but most people taking medication for bi-polar disorder, reactive depression and other depressive illnesses have their lives transformed for the better.

You could always try out 5htp first, then see a doctor if that doesn't work out. 5htp aids in seratonin regeneration supporting a positive mood and happier thoughts. You don't need a prescription for it either, you could get it from most vitamin shops. If that doesn't work out for you though, yeah you'd need to see a doctor or psychiatrist or therapist, whatever's in your budget (psychiatrists can be hella expensive).

You'll need a prescription. I recommend doing your research first before talking to a doctor and asking as many questions as possible. Depression pills react differently to each individual. So some pills might actually make you feel more anxious or depressed than you originally felt in the beginning.
