Grace, I also can understand what you're going through right now. I'm in a bit of a slump myself right now. But I'm trying to make small changes, like writing down something I'm grateful for every day and taking walks. It's hard to think of something to fight the depression for, like Adam suggested, but it's what I"m trying to do now, too.
I hope you're able to find a therapist sooner than three months (or the waiting list just magically disappears...).
Keep reaching out. It's encouraging to others as much as it's helpful for you.
