Brain fog every second

Everyone around me seems to accomplish something in their life. Dream job, family, partner, etc… I feel like I’m being stuck in this loop where there’s like a moment when everything seems like it’s going as planned, but only for a day pr two, then… months of pure emptiness. No time, no money, nobody to share my fears with and I always felt like I can do things only halfway good. Like there’s nothing I am really good at. I always drew in my life, but I feel like there’s a strange force keeping me tied at just one point and won’t let me surpass it, nor my limits. Not at least once. I am almost 30, some months ago my ex left, leaving me in a much more confusion and emptiness. But I always tried, and little by little, with my forces I improved in what she asked me, but she kept asking, and told me to hurry. Because she doesn’t want someone to carry on her back. And she’s totally right, and I always agreed that I’ve mistaken a lot. But I wanted a little more of her trust. The funny thing is that I already work, and she’s still only studying. Ok, it will arrive the time when she’s gonna work too, but she shouldn’t be in a much more hurry, I guess. I was forced to start to work since I finished school because my family is not wealthy enough. But one of my objectives was to enter university too. But right now I am not that able to do that. I always felt like mind is trapped in this forever foggy, cold forest. Not being able to find a way out, not even a light in the distance. So I wanted to ask if anybody else ever felt or is having a similar experience as mine.
