Its not just you kamil. Happens all the time to me too.
When you feel that nasty stall coming, try retract the flaps, as it seems to even more disturb the airflow and delay your plane from going nose-down to recover... and then push forward on stick in an attempt to get the nose down. If it still doesn't come down, turn the engine off, start kicking rudder left right left right in intervals so your plane begins to oscillate - hopefully, at some point in the oscillation your plane will swerve to one side, droop one wing and finally, get the nose down.
