Please help me diagnosis my manual transmission problem
 

The car is a 1996 Mazda Protege LX 5 speed manual. It is my only vehicle and I drive this car everyday!

My problem is the clutch, when I press the clutch pedal it will disengage the transmission, but only for a moment(enough to switch gears) and then it will reengage even if I have the pedal pressed to the floor. Additionaly, There is no loss of fluid?! I have been told there is air in my lines and that I should bleed the system. I also have been told that my clutch master cylinder is bad and possibly my clutch slave cylinder is bad. Has anyone else had this problem and can tell me exactly what I should do. I will purchase new parts if necesarry but right now money is very tight! I plan on bleeding the system this week to see if that fixes the issue but ounce completed, wouldnt air just find its way back in?! Thanks in advance to all that reply!

Sounds like the clutch master cylinder may have an internal leak. Similar to brake master cyls when brake pedal goes to floor. The last time I checked the price of a clutch master cyl, it was about $70. But that was for a Nissan Maxima
