I Have a Question

So about a year and a half ago I had surgery at 16. Since after I've suffered so much depression, and I really struggled to get back to my normal self as there was all sorts of complications such as infections after. Although my results were good!, thankfully. But I know I suffer anxiety and depression anyway but I was just thinking if maybe it affected me, having the surgery?. Has anybody else ever suffered the same sort of experience?. I feel helpless :(
