Hi Rainbow,
I think it's so great you're doing this! It seems so challenging to find resources that are a good fit.
In spite of the long ride, I really do like my day program in how flexible it is. They have groups monday through friday from 9 to 2 ( except on thursdays when they end at 12) but you can choose which groups work for you. You also don't have to go everyday and it's not time-limited. They do have a CBT/DBTT group on Wednesdays, but I'm gonna do only the DBT part because I can't stand plain CBT.
I don't know if others in the program have been in the hospital previously to coming. I know many have come for years and years. As long as you set goals every 12 weeks you can use the program as an ongoing source of support.
Good luck with this!
