I have a circuit out in my house that includes 1 bedroom 1 bathroom and 1 light fixture in the kitchen. I checked the breakers and tripped and reset all of them several times. There is no tripped breaker and there is no power to the forementioned circuit?

If the breaker is good and live then there most likely a problem where that wire feeds at the first tie in
Just to double check to reset a flipped breaker some you have to push it ALL the way off to it clicks it to actually reset it, not just flip it back
Was anything plugged in when this happened or a switch turned on?

Right away it already seems that there is way too much on that branch circuit. Especially the bathroom. It should be on its own circuit. Are there any Junction boxes on the way to the fixtures. There's a good possibility since a lot of areas tied in?
Has there been a new light put up recently?

I would first test the breaker on the load side to make sure still works.
TEST WITH BREAKER OFF
Look for junction box's and get to the wires and take wire nut off to see if they are tight wires together
Take some cover plates off and smell for a hot wire or see if you see a burnt discolored wire. Also check for wire nuts in any boxes and wire nut off to check good connections
Next Its unscrew the outlets and switches out and dangle on wires. Have an adult guard the exposed outlets and turn the breaker back on and use a tester or a light tester to see if the any power on any wires. We are trying to find the feed line. Once that is found then its replace a bad outlet or a bad wire nut connection. The wire nut can be tricky it might look good but the ONE wire to feed or an open Neutral will cause a problem
