Both. Sure we make huge progress in depression research and brain research in general, but there are so many environmental things happening, like yours for example, so just saying "oh yeah depression comes from that DNA" or "yeah that's just from your trauma. A lil therapy will heal everything" is just a bit short sigthed. So yeah, just saying that it's all very complex and we shouldn't really try to reduce this beast of a disease down to anything, because everyone has a different story. In the end I was just a little sarcastic, sorry
