My thoughts drift when I see sad stuff

I personally don’t believe I am a depressed person but when I see stuff that is sad or makes me think a lot, the topic of killing myself comes up a lot, I would never do it but whenever I see a sad TikTok or something it makes me think about killing myself not all the time, and it seems so weird to me, is that normal? whenever I have thoughts like that it seems pathetic to me but i don’t know, you know?

I don’t think I’m depressed but I also don’t know what these thoughts are or mean.
