Is anyone else soo tired

It’s tiring, frustrating, etc. That’s normal.
Peruse the forums and you will find some solidarity with other learners who have expressed the same sentiment:

Not sure what language you’re studying, but have a set amount of time each day to study and when that time is up, you’re done for the day. Learn to take breaks, write your own code/tweak the examples in the lessons, read the documentation, check StackOverflow and similar sites when you’re stuck. It’s unfair to tell yourself that you should be completely fluent in what is essentially a foreign language in a small amount of time. It’s akin to training for a marathon. Should you expect to easily run 26.2 miles on the first day or first week? No. I’ve said this before (many times): learning to think computationally takes time, practice, and repetition.

Keep at it and don’t get discouraged. You’ll get there.
