I know how you feel, I been there. I believe the reason you do this is because you enjoy it and genuinely want to help people so if people are to receive a video with slim to little chance of asking you questions about the content, that's still better than not receiving anything at all. You will still have done what you enjoy to do, helping people.
Do what you can when you can. I know it's easier said than done but it will be appreciated.
