Most adult relationships are an exchange of value, so don't dwell on the coldness of human connections

You need to be calm enough to accept losing anyone, any relationship. If no one actively reaches out to you, it means you temporarily hold no value in their eyes. Some people drift apart not because you did something wrong, but because you are temporarily not useful to them. Adults shouldn't live in an emotional world, nor should they view relationships emotionally. All relationships are an exchange of value and benefits. Of course, don't blame others either, because this is human nature.
