Does taking public transport affect your anxiety?

Public transport has never been something I have been a huge fan of and I will always try to avoid it if I can and walk places if I am able to over taking public transport. When I do need to take public transport and I am around people I do not know I notice that my anxiety spikes and I try to focus on something that will help for the duration of the journey. Luckily any public transport I take doesn't always take to long to get to where I need to be and finding something to focus on helps for that short journey.

Do you find taking public transport affects your anxiety? What do you do when you need to take public transport and you know your anxiety will be affected by it?
