Not passionate about things anymore...?

I will try to keep this as short as possible. During Sixth Form I got very stressed, and also lost my Dad and grandma, and I generally lost a lot of self confidence from moving schools, so I developed depression. This last year I have done my first year of uni, but it seems like I can't get out of this depression, even though a lot of time has lapsed and it seems like by now something should have changed.
At uni I had a lot of free time, unlike before, and I didn't know how to spend it. I didn't do any work for the first two terms, and I didn't go to many lectures, as I found it very unchallenging and unnecessary, as I recognised most of the theories and what we leant from A-level, and I ended up with a 2:1.
So I didn't feel all that passionate about my course or getting high grades anymore, since my outlook on their importance & relevance has changed. And I tried to go to societies but I just didn't enjoy them that much, and I didn't seem to click with many people, and I didn't feel like bothering to go. I've thought about changing courses but there isn't one that really appeals to me, and I've thought about what hobbies I want to focus on or what career I would feel passionate about, but I really don't seem to feel strongly about things anymore.
I think I have realised that I am pretty average at things in the grand scheme of things, and I won't be taking any hobby too seriously, so I don't see the point in them anymore.
It has resulted in me mostly chilling, and being quite inactive, although I do still go to the gym etc. It just seems like I don't know what to do with myself and even though the option is there I just can't bring myself to get stuck into anything and I would rather think about things more and go on the laptop or TV.
I feel so stuck like I can't get into a routine or keep busy, and I can't change. I also feel very stuck inside of my head, and not really "with it" or switched on to the real world...
I am wondering, should I just keep on trying out various things and keep doing what I'm doing - the gym and ice skating, and hope that I will fall in love with something again..? Perhaps if i had more self confidence and a better outlook I would see the good in things more? Or maybe I'm just worrying about it too much. I just end up thinking why am I alive.. I'm so untalented and there is nothing I really want to do or work towards, and I'm unhappy and just bored. I just need to find a way to love life again
like I will look at my boyfriend who studies maths and watch him talk about all of these complex theories and doing assignments, and it looks more difficult and challenging than what I do. Like I would just whip out an essay just to get it over with, or the multiple choice question assignments weren't hard either, and when we had projects it seemed like a matter of going through the motions, rather than a reflection of any skill... I feel so dumb studying psychology, like it's too easy and unscientific :/ but I don't know what else I would study...
Im not really getting anywhere with this....... I'm just living every day quite easily and feel a major lack of purpose or fulfillment/enjoyment and it's not going awayyyyyyyyy. :/ I'm too indecisive to know what to do about anything ugh.

Sorry this is so long, I'm amazed if anyone bothered to read it.
