I remember the first week I moved here... I arrived at H'row with 4 suitcases, a duffle bag, and a bike in a box. I could barely manage to get to a taxi stand and when i did, I had the surliest, nastiest driver. he was mad at me b/c I was going to a H'row area hotel and not the centre of London. Apparently there are buses for those hotels but I didn't know it. Though I tipped him well, he left me in the rain with all my luggage a good 10 feet from the sheltered entrace. I had to stay at the hotel that night, get the hotel BUS
back to H'row, take the H'row Express to Paddington, then take a train to Reading. Once to Reading I had to get another taxi. This driver was nice. He drove me to the Uni Hall I was to live at. But of course I arrived when the office was shut so he had to leave me with all my crap waiting outside. At least it wasn't raining! Once I got my key, I then had to schlep all my stuff up 2 flights of stairs to my barren little room. I was also dismayed to discover that hardly any one else was there yet so I was on my own, more or less, for a whole week. I was SO freaked out! And I had no phone!
But here's the funny thing. I had managed all that transport, with all that luggage but was still afraid of the bus. So my SECOND day there, I
walked to the train station and went to London for the day - including using the tube. I then took a taxi back to the Hall. I didn't get on a bus until I was with other people!!
So, don't be so hard on yourself! It will all work out!
