How you manage pressure about learning and the feel of getting stuck learning C++?

This is more about a point of view rather than a question and it's more about mental health and all that, I'm struggling really with burn out the last four moths, I feel like I'm close to be able to go to the real world to have a career in C++ but there is a lot of things I want to get well but is too heavy some times, I got stuck learning how to use boost beast for websocket to stream large binary data in message frames in async way, and there is way to understand and do it but I feel I cannot advance, I get so tired quickly and I don't want to get to other stuff, I want to finish this, but I was so tired, I want to have thing a bit right to start a real professional career and get financial Independence doing what I like, but I just feel I cannot, or better say it, I cannot advance more for some reason, I been learning in general for 3 years and I feel so lost still some way.
