Any of my tattoo people ever get a thought like wow, this is permanently on my body forever and freak out for a minute? Lol

I worry I will have mental health issues the rest of my life. Not sure I could live a life like that, Not really sure why I'm posting this, I guess does anyone else have the same thought?

Am I the only one who, when an unwanted thought appears, the heart starts beating very fast??

I can’t stop thinking about death today. Not like suicide or pondering how I could die. Just more so I’m going to die. It’s like. I was eating my pizza today listening to music and looking at the clouds. And I was like I love this this is amazing. And then Brain says “ur gonna die one day btw” Or I redid my wallpaper on my phone and I love the way it looks. I unlock my screen and admire the vibe I’ve created. And then brain says “one day you’ll be dead” When I feel a moment of joy or happiness or peace is when the thought screams at me. I’m really unsettled and distraught about thinking about being dead one day. This doesn’t come up often like other thoughts I have but I hate this one because it’s hard to cope with. Because I do the things and “techniques” to make them quieter. But then immediately Brain says “why are u even trying tho. It’s pointless because you’ll be dead one day.” Any advice ??
