You should try looking for what drives you. What motivates you? Is it friendship, nature, music or some sort of emotion? Draw based around that. I tend to find similar difficulties in my writings, unless I'm in just the right condition with just the right amount of a certain type of thought going through my head, because those precise things are what drive me to write. If you do enjoy drawing, I would take some time to relax, draw more casually. Listening to music as you draw may help, as that can relax you, or hype you. I don't exactly have a good idea for what you should draw, but I hope my advice helps.
Thanks and have a wonderful day,
