Hi UglyDucky

Yes, sometimes depression "just is"
Sometimes people can have everything going right in life, even everything they ever dreamed of but that doesn't make them immune from depression.............
But your T should be there to support you regardless so please don't feel guilty about seeing them, eventually you might discover an underlying reason or trigger/s with them.........something that can be addressed "head on"...........but if not they can still be there for you as a support in giving you a forum/safe place to "let it out", in helping you find ways of better coping with how you're feeling, in offering you ideas and strength in finding a way past/beyond how you're feeling right now
But if you're struggling with what to say to them............that's OK
Other than it being their role to help you find your words..........sometimes it can take a lot of less detailed, short or confused/mixed up, repetative, "simplistic" words/sentences............sometimes it can take a lot of pauses or silences in discussions to get to somewhere further...........often that isn't bad/pointless at all, but in actuality massive, real important steps towards "more"...........in fact even more than "more" because without those steps.............
So keep reaching out, hey?
And from me........kudos for still having hung in there with the therapy
