Trouble is not outside. A fine self-correction: "today I got out (ἐξῆλθον) of all trouble (περίστασις) — or rather, I threw it out (ἐξέβαλον)." The first verb would imply that trouble is an external place one leaves; the second corrects it: DOGMAit was not outside (ἔξω) but within — "in my TERMjudgements (ὑπολήψεις)." And so deliverance is not flight from circumstances but the removal of a false judgement about them.
"All is judgement." The passage is a terse formula of Stoic therapy (cf. Epictetus, Ench. 5: "people are disturbed not by things but by their δόγματα about things"; 8.47; 9.15 — things "outside the doors" are mute, the ruling part judges). περίστασις carries a military ring ("encirclement, siege"): the siege is lifted not by the withdrawal of the army but because nothing is left in the fortress to besiege. The governing discipline is assent.
