INFP and mental health

Madeleine

So I’m an INFP, and I deal with anxiety and bipolar. I also think very existentially. I used to be suicidal and deal with self harm. I’m just wondering if being an INFP makes you more susceptible to mental illness. Since I’m so quiet I don’t express my feelings much to people and seem closed off to others. Are there any other INFP’s who deal with mental health issues and do you think it has something to do with that personality?
