Touchpad mouse

My touchpad mouse on my laptop stopped working in the game, however, I can still move around in the game with the keys like forwards and backwards. When I got off of minecraft and the whole website, my mouse still wasnt working and I couldn't see it on the main screen no matter what I tried. The mouse is stuck in the game. Even when I uninstalled everything, I can't get it to move or use it at all. Its not my laptop as iv restarted everything. Also, when you press shift and a bar comes up with settings, options, save and quit, etc, that stopped working for me aswell. Please help!!!
