Help needed!

I try watching tutorials on doom builder stuff, but a lot of times they either don't explain the things I don't understand or they don't explain it in a way that makes sense to me. Is there anyone browsing this forum who knows doom builder 2 stuff and also has too much free time? Wondering if someone can do a one-on-one chat with me when I need help with that stuff. Sorry if this is a stupid request. I just don't get it when I look it up online and feel like the best thing for me would be to have someone right here with me, but unfortunately I don't know anyone in person who knows doom builder stuff, so the second best thing for me would be to find someone online to do it over the internet. I really get confused super easy with this program and again, the tutorials I find usually confuse me too. One thing I am having major struggles on right now is doors, but I am sure there will be more things along the way that I need help with.

Please help. Thank you.
