I've recently discovered that my mom is ISFJ. She's a great person and wonderful mother. One thing that makes me sad though is how she seems to have extremely low self-esteem. She will put herself down a lot and say negative things about herself. No matter how many times I try to tell her the opposite it just seems like she doesn't believe it.
For example: She doesn't know how to drive. She often mentions that she wishes she could drive to go to the store, visit my brother at the cemetery or just have a little bit more freedom as to not have to depend on other people. When others express their interest in teaching her how to drive she will immediately say something like "I'm too old to learn anything new," or "Your brain is much better than mine, I'm not good at learning anything," or even "I'm just not good at anything."
Is very low self-esteem common among ISFJs? And if so, how can one help you understand how wonderful you people truly are?
