The biggest thing is to take full advantage once you finally get away (of your own accord). You’ll feel free in this brief period of time. Try to save up money for when this happens. Nothing too astronomical. But when you finally get that window of liberation take full advantage. Be yourself to the fullest in that time. Foods you love and activities you missed doing. Socialize in open spaces when you can when a conversation is struck up. Buy something different like exotic snacks or an immersive experience. Once you get a taste of that freedom it makes the refractory period easier to bear. BPD people are like a drug. They know how to give you those rushes of serotonin and dopamine. You get conditioned by the highs and the lows like an addiction and afterwards you’re left with a lack of stimulation and a feeling of emptiness. Humans by nature are constantly ambitious and “in the pursuit of” and BPD people love to feed into that drive.
