I understand this situation a hundred percent. The only difference is I'm physically fit and have a permanent work. Although the pay is good, and together with the funds I'm cashing out from Steemit, sometimes it still doesn't cut it and I still have to earn more. I have the same issue. I only draw on paper, an entry level phone, and a laptop that was borrowed (i don't have a touch pad i only use a mouse); I could really use a device that has a pen so that I can draw better, but finances doesn't let me buy one. Here's what I can advise. Set your priorities first. I feel you're an amazing artist, the medium only helps with the art; it's the heart that makes it. It's you who make the art, not your gadget. Some artist try to be resourceful and even go over the limits of their medium. If you can make it with what little you have now, it will hone your skills. You don't need an iPad Pro or a Surface to create art. You just need a creative brain, a heart for art, and tons of perseverance. Time will fly and you won't notice you have a workstation of your own. A big Wacom and high end PCs. Be brave, don't stop drawing, you'll make it with flying RGBs and CyMgYs (don't know if that's right). Cheers!
