Congrats on trying! I'm coming back too. I know what it has been like for me to hit plateaus at times (I'm in one now). I think this is how change works...we get spurts of motivation...then plateau...then change again. Don't give up hope. DBT is helpful, but doesn't always make people feel better immediately. Some questions to ask yourself: are you expectations for yourself too high right now, given having major stressors? Can you not always be improving and still be "ok"? Is it ok for your boyfriend to be wounded, needing your support?

Good luck with your mood...I hope you find as much support here as you desire.....
