The situation that you are in sounds really difficult. I can't imagine what you are going through right now Do you mind sharing a little bit more about what you mean by 'the human condition'?
Sometimes when we can't talk to those around us, we reach out to professionals instead. This could be a GP, a psychologist, a counsellor or someone else that you trust. There are also online counselling services like Kids Helpline and eHeadspace. Do you think this is something you would be open to doing?
