When you are out the back, do you lie prone and jump up with the wave approaching?
At my 97kg, I tried this summer a 84l 7'10"x 27 3/4" Imagine Impact, and I definitely could not stay upright more than 30s. Basically I had to be hyper-focused and as soon as my focus loosened, I fell. Thus trying to paddle around, then positioning to get a wave was too hard because the change of focusing would make me fall.
I then just lied prone and stood up when seeing a set approaching. This way I was continuously concentrated on making the wave and di not fall or miss a wave. Alas, once on the wave I was so mentally exhausted from the take off that I did not really surf better than with a bigger board...
But turning to get the wave was not an issue as long as my focus was not disrupted. You should practice.
Also, on very small board, you must put your front foot very close to the stringer, and away from the rail, as possible. Having the front foot close to the rail will bury it on takeoff. This may be your problem.
On flat summers, I sometime fought the boredom by trying to SUP my 70l 9'1"x22" surfboard. This is an excellent workout, exhausting and an excellent balance practice. I was very proud of me when I was able to be able to stand up for 10s, paddling furiously, only to hear a kid tell his mother: "look, the guy is so fat he sinks his board" :-)
