Thank you for all the replies so far.???????? I hate to say this but my embassy is known to be one of the worst here in BKK. I already asked them for a document and I have been told to just wait for my passport. Giving me a document is pointless according to them as I would still need to pay my overstay if ever. Some people said just show the receipt of processing and receiving my passport, then show it to the IO in the airport so they'll know I did not overstay intentionally. I have no problem paying the fine as in my situation it's inevitable.
Once I have gotten my passport, I plan to go directly to Suvanabhumi and pay the overstay, then leave for Laos. Since I don't have any stamps in my passport, what would they do?
I did not choose the travel document because going back to my country would be a lot harder. Yes! They make it harder for their own citizens to acquire documents, passports, visas etc... The embassy offered me to expedite it for a fee which I paid, as they said it will only take 3 weeks. But it's past a month now!
I really do appreciate all your inputs. I came here as I know there would probably be more people knowledgeable with my situation and could help me in whichever way. ????????
