Correct test?

So last night (oct 3, 2018) I took an online test about depression and anxiety and bipolar depression just to see and “check up” on myself. Plus I was pretty bored. So I decided to take some of the tests and the results came out that I have severe depression and my anxiety is super bad. But my bipolar depression test didn’t come out as bad. But I was just wondering if you think these tests are close to accurate. (Please note that I answered truthfully, and I am 13) I don’t know if I should talk to my parents about it, and I feel like I’m making a big deal out of this all. Help!💗
