If you are building your hardest software yet there are few golden rules. First of all you need to be sure that what you are doing it is worth, take a break and look at your project from a different angle, it is still worth working on it ? Keep it simple, look at any single piece you have already build, it is necessary ? Why ? It is really necessary or is a "nice to have" ? Focus only on what is necessary, the "nice to have" will be put in place later. Why you keep find it so "taxing" ? Have you switched paradigm ? (OOP->FP maybe ?) it should take a while, but not too long, if after a couple of months you are not comfortable yet you may consider to be sure that you have really understand what is going on... If you are still going it is worth for sure... Keep it strong :)
