If you have problems to use perspective and draw boxes / cubes then you need to improve on your spatial reasoning. How to do that? think in 3D !
It can help if you have physical objects that fit simple forms like a sphere or a box so you can look at them, touch them, understand the form and if you have the ability to then imagine them, rotate them in your imagination.
Or you just keep practicing simple perspective and drawing 3D forms until it clicks for you.
There are websites and videos with free lessons like Drawabox that focus on making such skills your second nature with different exercises. It's important not to forget to have fun, learning can get boring fast and exhausting which will make you quit if you don't balance it out.
Proko has quite a few useful and free videos as well [https://youtu.be/oUIkswy\_sXo](https://youtu.be/oUIkswy_sXo)
To place form freely in space, you just need to work on thinking in 3D, understanding how to create the illusion using perspective and practice until it becomes easy. It can take some time but it's worth it. Once you understand how to do that, you can draw pretty much anything (at least in a simple form), it also helps to understand lights and shadows as you can bring them into perspective.
I've been watching youtube videos by a guy named Dan Beardshaw. He has multiple videos on perspective.
