These two give me problems. I get too anxious and I get this unrelenting tunnel vision. When I play normally on standard, I'm able to play at a much higher rating. However, the discrepancy I believe is far too large. It blows my mind. I lose to 11xx rated players in bullet. 

Bullet/TT ~ 11xx elo.

Standard 16xx~18xx.

the rating pools are different so dont correlate

also bullet is also very related to mouse speed. You can only really use bullet as opening flash card type study ... totally ignore its relationship to chess its non-existent

Bullet doesn't measure chess strength, it is a test of the speed of your reflexes - and your equipment and connection, as TonyH notes.

The slower live time controls you play, the more reflective your rating will be of your strength of play.  But remember that ratings never measure strength - not here, not FIDE, not USCF - they measure results only.  If you have a good number of games rated at slower controls, it will be closest to a measure of strength, but even then it isn't, directly.

Online chess is the equivalent of "correspondence" chess, and is an entirely different game.  Skills and experience acquired from both forms can help your play in the other, but they are not directly transferable.

Tactics trainer is a good exercise, and a lower rating in it just means you need the practice even more.  It doesn't "count" as a rating, though.
