My toolkit has changed somewhat. I have a much better phone now and I have pictures of my kids to look at. I don't carry earplugs most of the time. I hardly every use my iPod in public now. Though, I will say it's likely because I choose what places/events to go to with more mindfulness. I'll go early or late as needed to minimize feeling anxious or claustrophobic, or I'll have a safe person with me.
When really struggling, I'll fall back on my basic toolkit and do better self-care management. I have a much better internal tool kit which serves me well in most day-to-day things.
