I've been having a lot of issues staying motivated with drawing over the last few years. The main issue being that I don't find much of any improvement in my drawing skills for a very long time now. The reason for this is that study constantly eats away at the time that I would much rather invest in practicing art.

I've often tried to build up a practice routine to practice the fundamentals of drawing. However every time I do that a few weeks later or even less study takes over and I have to drop everything I worked so hard on. To me it than also feels like all that time that I invested was for nothing, that I made no progress at all. This has been happening over and over again. Every time I start up again I have to go back to the beginning of the exercises. It made me lose hope on ever moving on from those beginner exercises, and thus on ever becoming better at drawing.
It also keeps wondering if I'm even doing these exercises the right way, that I'm doing them incorrectly which is why I'm not improving at all.

Since study kept stopping me I also constantly worry about the next time that it will stop me from drawing again. It feels to me like there's no point in even trying because soon again I'll be stopped again and whatever progress I made would be lost again.

That is the true reason why my art productivity has been constantly declining.
I want to get out of it but my worries keep me back.
I tend to get overly emotional when I get back into drawing as a result, which makes me hate myself even more.
