I don't think it is possible to really know anyone because I think there is always a private part to every person. Furthermore, I don't think people really are anything, other than their behaviour, thoughts and physicality at any moment in time. Everything can be changed or broken. It's all constructed and put on like clothes, layer by layer - personality, likes, love, behaviour. It can all be stripped away so there is nothing to know really except what front a person chooses to wear at one time - which could easily change. It's a facade of convenience to hide the empty centre.

But I've no faith in my feelings as I'm someone who suffers from poor mental health and the sort of feelings that go along with that.

So - no, but I've no faith in my feelings.
