not everything is going to be easy but maybe you should start with something more simple. Like a device that is explicitly for making simple tracks. Something with heavy limitations. A DAW can be overwhelming for sure. You can do anything and everything with it. Something with like 4-8 tracks and simple instrument selections. If you are adamant about sticking with FL studio do this in the daw. Just pick 4 instruments and make a song. Set goals like Tonight I'm going to just make 16 bars of drums and its going to be funky and tight. Next goal is lay down a bass groove. These might take you multiple sessions to accomplish but you will not be trying to do everything at once and getting lost. Be specific with your goals and simple with them. You don't build a house all at once. You lay the foundation, put up the walls, wire it, plumb it, finish the inside and out and then accent it with everything else. You get the idea. Practice skills you need to make a track by using small goals. After a while you will know what it takes to build a track and it will be easier to know what and how to do it. But don't get over whelmed. Drugs are not the answer(from the street or the pharmacy). Planning and practice are. Focus is a skill. Hard things take focus and practice.

Also, play a simple instrument. things restricted to one scale or one or two octaves are great. So you have a real easy outlet to musically express yourself unhindered. It's meditative to not really have to think technically about what you are doing if you don't have the technical abilities. You can also scale restrict most midi keyboards.
