Is there any other foreigners at the gym on ED visa? Have you been to the gym yet, trained there yet? You might want to consider switching to Thai Language ED Visa in Ayutthaya. I think this option is possible. Also explore northern Bangkok for MT and Language ED Visa options as its 'not far' from Ayutthaya- maybe face to face one day and 2 online lessons per week will be OK. Hope this makes sense.
I did it a while ago. When you get your passport back jump in a tuk tuk outside the Embassy and go to Savannaket bus station- 3 minutes away. Get the 14:30pm bus to Mukdahan bus station, this will take you all the way from Laos to Mukdahan inc. stop for border crossing. The bus will drop you at bus station with a 4:30pm connection from Mukdahan to Mo chit.
