Welcome, Laura, to psych central. I hope we will be able to help you on your path of healing
Yes, depression is tough isn't it? As we progress in therapy we learn WHY we tend to lapse farther into the darkness at times. Try not to fear the future (as in, darkness to come) but live in "today" if you can. My T says that THAT is the time we are real, that is our real life, and when we do succumb to the darker times, that's the depression - not "us."
Come back and post often! TC
