Have you talked at all to a therapist about the situations and what they could be triggering that makes you so anxious? It is great you have been able to observe the sorts of conditions that cause you to respond in this way. Just understanding where they "come from" won't necessarily make them go away but I found it was a "comfort" to me so I was less afraid of being afraid, knowing a situation's basis and thus having the opportunity to plan ahead a bit for better support and management.
