I'd echo another post saying don't underestimate your depression and/or ADHD. Some (many?) people suffering don't even realise the extent a lot of the time.

I also took note of you describing your DnD buddies as 'your partner's friends'. I mean you've been going out for years, they must be your friends now? I found that a bit odd.

Anyway, temper what I've said with yeah, you're not necessarily supposed to have it figured out yet.

I've been through all kinds of therapy and also Neuro-Linguistic-Programming (I'm sure some will think that's a fad or whatever, fine) but certainly have a think about setting some professional goals. You must have a vocational interest by now.

Set short term goals. I am into Computing and went through some free and paid for online courses (properly!). Half-decent ones, not crap.

In Computering we're able to get Certs as well, so that was another achievable, tangible goal.

Finally make a habit of reaching your goal. Going all balls to the wall for 1-2 days, or even over a week is not sustainable. It's a lifestyle thing - an hour or whatever a day - forever. Get used to it!

So yeah, think about your vocation and what you need to achieve. And take steps that you can measure.

Won't comment on the rightness or wrongness of your end goal, but I am curious as to why you are failing to study?

Fs mean you aren't putting in the work. So what's going on?
