Don't worry
Assuming it takes all countries to pass legislation before it goes into force, you can rest easy since the US is unlikely to pass it anytime soon, if ever. The republicans, who would normally be in favor of anything claiming to be "free trade", have a lot of members very suspicious of it because it was negotiated under a democratic president. A lot of democrats, who would normally be in favor of something a democrat president is backing, have a lot of members very suspicious of it because of worries it will cost jobs in the US (and it doesn't help that said president is only going to be around for another 13 1/2 months anyway)
If Clinton wins, it probably goes forward IF she cares to push it, if a republican wins they'll probably press to renegotiate some of the terms they think weren't free trade enough, which would likely derail the whole thing.
