I was diagnosed with an adjustment disorder, though there are some other issues at play. Not sure what exactly (haven't asked and T hasn't offered) but probably depression and attachment issues. I've been seeing my T regularly for about ten months now and I think it started to help within a month or so. It's small changes that add up so it's sort of hard to define a time frame, plus my stress levels vary. But I think I am definitely coping better now than I was a year ago. So yes, it helps, and I would recommend it especially since it sounds like you're in a pretty rough place right now. Hope things get better for you--good luck.
