TIFU by jumping head first into a lake

So I, given the end of my GCSE exams, wanted to have some fun. I flew to my grandparents and am now with my friends in Poland. We went to the lake nearby to go swimming, and I know how deep it is everywhere where we go swimming. I jumped into the lake head first at to great of an angle into the shallower part. My arms hit the ground first before my head hit it shortly after. My nose and lip were bleeding after I came out of the water, but not to raise any worry I stayed in the water and kept swimming and having fun. In addition my neck and forehead were slightly hurting.

I do feel alright as I'm writing this, still by the lake, but shaking. I don't want my grandparents to be worried or anything so I will say that i had an accidental, for example hitting a lamppost or maybe stating I was play fighting with my best friend, and he hit me twice in the lip. This too, was my closest call to death, or paralysis, but luckily my arms absorbed most of the impact.

TLDR: I hit my head on the lake floor, have a few minor injuries, avoided possible death as my arms absorbed most of the impact.
