This was me. I BC'd, shaved it all off to get rid of all my relaxed hair. I should have transitioned. I could do nothing except a wash n go, as it grew. The SSK's drove me nuts. My hair would not grow because I kept cutting off SSK's that never seemed to stop coming. Frustrated to no end, I relaxed last month.Short hair is really tough. You do have to choose relaxer or natural. There isn't much in between. Hang in there. My hair is 4C also. When I transitioned, I was all about the twistouts and the occasional strawset. I couldn't do anything else. I'm not sure how short your hair is, but if you can twist or braid it or do a strawset, it may help you stretch longer.
Good luck with the lock down. I hope that your numbers come down on time and everyone can get out to more places soon. I am concerned that we will return to that in my part of the US.
I initially planned on at least growing out my natural hair to shoulder length, before I considered my next steps (staying natural vs relaxing again), but that didn't happen. Now, I'm left feeling like I shaved my hair off, with super short hair for a year, with minimal progress, for no reason. smh
