Reminder: you probably have a person in your life who is carrying a long term resentment towards you and will betray you at your lowest.
Do your best to figure out who that is now.
I have a feeling that the signal could be in the form of understanding “who is leaching my energy slowly?” If it is a truly resentful person they might draw from you until like you say you are at your lowest…then boom betray you because you’re not a good “host” for their leaching no more.
