Motivationless and a bit disappointed

I joined this site last year and I try to do at least one step every day. I managed to find a psychologist and soon I thought I would be almost making anxiety and all the other I'm struggling with disappear. But as of right now, I feel kind of empty, even though my anxiety levels are lower than what they used to be. Some of my issues:

On the anxiety side, I can bring myself do more stuff that I wouldn't be able to do because of fear, but I'm still holding myself back. When I went to college to take an exam, I didn't feel confident I would pass and even though I could've just simply taken it and fail it, I couldn't and I literally stopped in front of the door where the exam was taking place, turned around and went the way I came. It's like I was sure I would fail and that made me nervous. It's like, I saw changes within me when I'd been going to the psychologist, and I see them, but I still feel melancholic, oftentimes at night when I know go to bed at 2AM, even though I want to go at least at midnight.

I feel like my self-confidence hasn't shot up like I hoped it would've, whether it's trying to stop cringing at my embarrassing memories (even though rationally some of them weren't even notable or embarrassing) or improving my posture and attitude. I used to have lots of hope, and I still do, but now I oftentimes feel melancholic, motivationless, just wasting time away doing nothing useful. It's like as soon as the heat came around, my energy level dropped down and since I expect myself to doing something, it's discomforting, but when I try, I either getting distracted or too wore down by weather to care. I tried writing down tasks that I needed to do, but a lot of the times, I couldn't do any of them. I've decided to slow it down and do like 3 of them at a time and that seems to work a little bit on the emotional side, so I have that going for me.

When I started taking therapy sessions last year (around this time), I was optimistic that I would make big progress, but right now it feels like I've regressed and it disappoints me a bit. It feels like after sort of a high I felt in the Fall, I became sort of moody, but still having lots of energy, but as of around May or June, my energy levels fell and I just can't be bothered that much anymore. I still do stuff, but it feels disappointing to look at stuff I'd done before and stuff I do now. Combined that to the fact that I used to try to socialize (which I'm kinda proud of) and I don't do it all that much anymore. It seems like a combination of weather (which is hot) and high expectations and I just can't meet them right now. I don't know how to feel right now so if you have any advice, I'll gladly look at it.
