Does anyone else ever think about their life and get freaked out?

Sometimes I sit and think how amazing it is that I am me and that I am alive in this world. It is surreal and I want not think about it anymore but I have been obsessing about my life and how we all are going to end up dieng some day. Can anyone give me some tips as to how to stop this? Let me know if you feel this way too because I feel like I am the only one. Thx have a good day and I hope you all are enjoying life!!!!
