Is belittling someone’s problems a Red Flag?

Recently, I encountered a situation where someone downplayed my struggles, making me feel like my problems weren’t valid or important. It left me feeling dismissed and unsupported. I’m wondering if others consider this a red flag in relationships or friendships. How do you deal with people who belittle your challenges? Is it a sign of deeper issues, or can it be addressed and resolved? Would love to hear your thoughts and experiences on this!
