@GumballMachine your question what is synchronicities may be explained in wikipedia
"Synchronicity is a concept first introduced by analytical psychologist Carl G. Jung "to describe circumstances that appear meaningfully related yet lack a causal connection."[1] In contemporary research, synchronicity experiences refer to one's subjective experience that coincidences between events in one's mind and the outside world may be causally unrelated to each other yet have some other unknown connection.[2] Jung held that this was a healthy, even necessary, function of the human mind that can become harmful within psychosis. https://en.wikipedia.org/wiki/Synchronicity
I am not an expert but only a peer supporter. If you are in great distress and your situation is disrupting your life, you may find greater support with a professional mental health counselor.
I think this is an interesting topic but if taken too far, one may think that one's mind is causing things to happen. If you care to you can share more here and may get other's opinons. But remember a professional is more suited to helping you sort things out.
