Most of the year, I live with a roommate. It is immensely helpful. I'm busy the whole day and really don't get into situations where I can fall except at night. When there is someone else in the room, that gets eliminated as well. However, for Sukkos I am in a room by myself. I had a really long streak going, and then fell right before sukkos. I've fallen numerous times since. Now I'm beginning to ask myself if I really made any progress or it was just a matter of inconvenience as to why I didn't fall for so long.

When my roommate gets back, and I start another streak, is that even going to be meaningful,if I'm just going to fall the second I'm alone anyway?
I just can't believe I fell the day before the hoshana raba. Unbelievable.

Hatzlacha raba everyone

it's very believable.
you should have seen what was going on here a day after yom kippur, with people falling like flies [myself included  :-[ ]
everything you do is meaningful [even falling]

GET THAT.

Rav Hutner explains the pasuk שבע יפול צדיק וקם
different than most of us understand it
we think it means that despite falling 7 times the tzaddik keeps getting back up
He says thats not what it means
rather the tzaddik becomes a tzaddik because of the 7 falls!
You can learn from each fall about yourself about what works and what doesnt and how to prevent future falls.
Nothing is meaningless.
For the record I've been motzi zera while people were sleeping in the same room
as they say where there's a will theres a way  ???
so be thankful that other people in the room still works as a deterrant for you.

would you say that someone recovering from breaking a leg who uses crutches isn't really walking? he's using whatever he needs to rehabilitate himself. we do the same. use whatever works, and build on it. Instead of negating your accomplishments, use it in the future to convince yourself that you can succeed or to act as if someone is in the room by reenacting the feeling that you had when  someone was actually there. just a thought. use your imagination to figure out what works for you, I can only talk from my own experience.

keep up the fight, dont give in to the YH's "pep talks"
