idk if this happens to anyone else, I feel crazy rn. I'm 21 and my parents are in their early 50s and pretty healthy (thank gosh) but out of nowhere I just got hit with a wave of anxiety about them eventually passing away one day. I don't cry very often but I'm laying in bed crying rn. I'm missing them a bit bc I'm pretty far away at college but it's my last year so nothing new, I shouldn't really be homesick but I am. they're my absolute rocks and I'm so close with them, I can't imagine life without them. I genuinely don't think I could survive them passing although I probably would. what are some good ways to calm down about this? I'm making myself so upset.
