I woke up early, and endeavoured to get all my options ad requirements listed out. Clara and Jean-Marc left, after we made some jokes about Suzies being like Hotel California - once you stay you can never leave!
I didn't have an appointment but headed over to the British High Commission anyway. While I was out, I tried calling the Thai Embassy and other agencies to be sure I was doing everything right.
I got to the High Commission, and was unable to see anyone in person, but was able to use the phone in the reception area, where I was advised that I needed to fill in an LSO1 form, book and appointment, and come in with evidence of tickets for travel. I was advised that I could not have the passport sent to the High Commission in Malaysia, and so I started to make plans for heading to Thailand with a view to having the passport sent to the embassy there.
I headed back to the hostel, and got to work, trying to figure out the best way to manage the Thailand part of my trip. It was going to take 4-6 weeks to get a replacement according to the government website.
The other things I had to do was obtain a police report for the lost/stolen passport, and once I get my emergency document, get that stamped by immigration to allow me back out of the country.
I filed the LSO1 form while booking the appointment, and the information on that page indicated that I didn't need a police report as I was not reporting it to be stolen. The appointment booked for the next day, I then proceeded to book the flight to Phuket, and the bus from Bangkok to Siem Reap in Cambodia.
I now had most of an itinerary for Thailand set up in my diary, and evidence of travel, so my next steps were to get the emergency travel document, then go an apply for a Thai Visa for my stay there, so that I could arrange for the replacement passport to be sent there.
