Getting There: My Transit Plan

I have [How You Describe Yourself] and getting somewhere new is stressful because I don't know what happens if the plan breaks. I need to get from [Starting From] to [Going To] by [Need To Arrive By] using [How You're Getting There]. What worries me most: [What Worries You Most]. Help me: 1) write the plan as numbered steps, including where to stand, what to look for, and how I'll know I'm at the right stop, 2) give me a 'what if' for each step — the bus doesn't come, I miss my stop, my phone dies, 3) give me three sentences I can say to a driver or stranger to get help without explaining my disability, 4) tell me what to put in my pocket before I leave, 5) give me a practice version I can do the day before. Be specific and literal. If you don't know the actual route, say so and tell me exactly what to look up.
