I am seriously questioning my mental health?

i am 15 and for all my life i have had urges to do crazy things, on planes i have urges to open the emergency doors, on tall buildings i have urges to push people off. the other day dad got me a steak, bacon and cheese pie, and i remeberd a song's lyrics "gargle with proxide, a steak for your eye" and i had a super strong urge to smush the half eaten pie against me eye, it was all i could do to resist it. also, sometimes i am happy but most of the time i am soooo depressed, and it just swaps, when i talk to dad about things like this he thinks i just want attention and never ever takes me seriously
