Hi Adina!
I agree with Steve and his excellent advice. Don't give up just yet.
Remember if you have Software Playthrough activated and press r to record
you have a constant input signal. Then you can go through Steve's chain
and you'll hear any changes in real time. Make sure to plug your
headphones in at the end of the chain. That's to say, directly into the
computer. Good luck!
Cheers, Robbie

Think of the equipment as a "chain". For voice recording, the chain begins
with your voice, the next link is the microphone, the next is the input of
the mixer, the next is the channel "gain" (trim) control, then the channel
Eq and pan, then the channel level control, then the main mix control,
then the USB 202, then the computer sound settings, then Audacity and
finally to the hard drive.
Excessive hiss usually indicates that the signal is too low in one part of
the signal chain, and is then being amplified too much in a following
stage of the signal chain.
Note that the microphone must be plugged into the large 3 pin XLR socket
and not into a jack socket.
Setting the gain level correctly is difficult as this is normally done
from visual cues on the mixing desk meters. As a ball park figure, try
setting the gain about 3/4 of the way up (turn it up full and then back it
off a little. If the gain is set too low the recording will have excessive
hiss. If set too high there will be crunchy distortion on loud parts. The
noise level will also probably go up if the gain is set to maximum.
Ensure that you are close enough to the microphone (try about 10 cm but
place a pop shield (wind blast shield) between your mouth and the
microphone.
Work your way through the chain from start to end and check that
everything is set correctly. If you are unsure if it is set correctly,
work on one thing at a time, for example, try turning the gain a little
higher - is that worse or better? Then try turning it a little lower - is
that worse or better?
The high and low equalizer settings probably need to be set at their
centre position - there is probably a slight "notch" that you can feel
when turning the tone controls past their centre positions.
