You might want to arrange a "Rainy Day Action Plan" with a family member or close friend that you trust.
This would involve you writing a list of stuff that you do and don't want to happen if people ever feel the need to provide treatment. It can include signs to look out for - that mean things aren't going well and that people should take action.
I'm not going to do any kind of diagnostic stuff but early intervention is important.
EDIT: obviously, you should see a doctor rather than relying on Internet advice.
