I'm so sorry to hear what happened.
And it is really sad that no one called or checked where you are and especially knowing about your problems.
Could you try to find some support from your friends and rely on defining some scheduled talks and checks as sort of precautionary measure?
I can't judge people around you but simple fact that this is not the first such situation speaks more than enough.
Please try to find some support and care outside of people who are not supportive.
You can count on us here also!
