The obstacle shows up as a contradiction: the person wants to be alone and takes offence when they are left alone. They push others away and expect them not to go.
The people around read this as inconsistency and in the end really do leave — which confirms the person's worst expectations.
What it blocks is the capacity to stand alone. Behind this point is someone who can walk their own path by themselves and afterwards show others the way; but genuine solitude does not take offence, and this one does, which is why it does not work.
What to do: say plainly what you want right now — to be left on your own, or for the others to stay. Here that settles almost everything.
