You're overthinking it; the matter isn't that serious.
Tips
mistakes
Don't confuse 过虑 (guòlǜ, to overworry) with the homophone 过滤 (guòlǜ, to filter). Different second character - 虑 (worry/consider) vs 滤 (water radical, to filter liquids). Spell-check apps often flag the wrong one.
usage
Often used in reassurance: 你过虑了 ('you're overthinking it'). The synonym 多虑 overlaps almost completely; 多虑了 is slightly more polite and literary.
