How to type unhealthy mbti individuals?

To be blunt about this question, I have no idea how to tell if others are a healthy type or unhealthy type. So I was wondering how others type those unhealthy types because I don't know how. For example I am an unhealthy ISFP 4w5 where I used an addiction to escape stressful situations, unwind, keep positive energy going, etc instead of making it into something I can do hands-on to express those emotions (still working on those issues and have no idea how to handle it).

​

I do have a slight idea on some types given how I put it in a certain but simple way. I/E: Do they prefer group or solo activities, N/S: Do they prefer planning for their future or let things happen in their life, F/T: Do they make decisions based on their emotions or purely on pros and cons, J/P: Do they have strict routines and rules to follow or are they flexible and adaptive to new plans? So far I've gotten a few people typed out but don't want to assume they're unhealthy in case I could be wrong about this typing system I created to help socialize better, even if I'm still growly and hostile at times.
