Clutch is sticking to floor, sometimes it will not come back up Options

[pnoywitmustrdsau...]

I dunno whats going on with my clutch pedal and it just started doing it a month ago. here are some instances of what happens. at a dead stop like me waiting at a light i tend to press and hold the clutch pedal down and wait while im in gear for the light to turn green. when the light turns green i release the clutch but it will not come up and i would have to use the tip of my foot to pull the pedal back up. second instance is sometimes when driving under normal conditions i'll shift normally and the same problem happens between shift usually around 2, 3 and lease 4 gear! what could be the problem? i did check for fluid and i did bleed the clutch and it seem to work for a day or two then it came back? any feedback would be much appreciated.
