Black out three sides of his 10 gallon tank with construction paper taped to the sides for more security.
Stop handling him for now.
Add another hide on the cool side for him to feel more secure.
Upload us a picture of him on the ground next to a dollar bill if you do not have a gram scale to weigh him.

The temperatures should be bumped up as well but we can deal with that after the pictures. Do not plug in the heatpad without a thermostat or rheostat attached to it.
