Yeah, that's the thing about singling out behavior, they literally could be signs and symptoms of over a dozen diseases or just be totally normal!

If you've been seeing your present T for a while and this person has done a thorough assessment, then of course what they say has more credibility and you might want to really consider their view and look at the evidence they've used to draw this conclusion. If you want, get a second opinion too.

But myself, due to depression, I do get into different hobbies and interests, sometimes more quickly, sometimes not. I think your average person also has a variety of interests and can go from hobby to hobby. People are not robots! One of my friends, who is mentally healthy, is quite artistic so this person too engages in a lot of artistic things, based on how the mood strikes them.

In my case, whenever depression lifts, I find the strength to go after one of my interests but then it hits me again and I give up. Sometimes I wonder if the thought of going after the same hobby or interest just reminds me too much of my failure, so I just go after another one of my hobbies next time I feel better.
