Hello (M) it’s Gandolf here.
I’m afraid that your sensitive nature is always going to come up against certain family members who challenge you.
This isn’t really a lesson as such, more of an acceptance that some people are reactive and liable to be confrontational. This doesn’t mean that they don’t like you or wish you ill, but it’s their way of releasing frustrations.
A good idea is for you to challenge them back in a kind way. They would like that and it would certainly make you feel better.
