Bliss Theme is catchy and does remind me of some nice summer pop numbers.
Anxiety Theme's tonality does convey the anxiety well, and those spicc strings are the star of the show. Initially I wasn't quite sure the guitar got my hair standing on end. The strings and piano certainly do it for me though -- a tension in the air, a tension I can almost grasp.
The ending theme does sound like you're looking back fondly on something.
All in all, a pleasant listen, and you should be proud. Well done!
