Brain deactivation?

Question

IT education

Does it happen to you that you study, study, program, develop in mathematics, it seems that you get more and more, you develop logic, thinking, creativity, you feel how it improves. Everything is on track. And then one day, once, and everything seemed to go "on knurled"! It's like you're dumb. Tasks of that level of complexity that you could solve before, now you solve them like a slow-witted one. Thought processes and the construction of algorithms began to take place somehow less clearly. Some kind of fog or cobweb forms in the head. And panic begins, the fear that all the knowledge gained by labor disappears, and the brain atrophies. Worry that you won't be able to get the profession you really want to get. It's just a shame that you are fighting so hard for a place in life, trying, learning, and the more you fight,
Some kind of paranoia begins: you are afraid to walk the streets somewhere - God forbid that you breathe the smell of smoking people, which can harm the brain, maybe you ate it wrong and from the fact that all sorts of rubbish is put into our usual products (antibiotics in dairy products, growth hormones in smoke, etc.) mental abilities decrease, and then you get even more upset and think that you are even more stupid. Or maybe it just seems that way?
