Very first time completely clueless please help!

Hello everyone my name is Annie this is the first time that I entered this community chat I haven’t even finished setting up the account. I have no idea what I’m doing. I’m just taking a shot in the wind. I live paycheck to paycheck and I’m really looking to make Some money that can support both me and my older son Who can’t work because he’s in stage of recovering right now. I really want to get into this e-commerce stuff I just looked at what’s needed to start the store and just looking at that it gave me anxiety. I have no idea I had to fill out the information the right way. This is so overwhelming. It’s not easy as they say you actually need somebody that knows how to work this Shopify system Even with their directions I still don’t know what the right answer is other classes that I should be taking for e-commerce I’m here and I don’t know what to do. I have no idea what the hell I’m doing. I saw a little bit on eBay that’s easy for me. I don’t even do international because that’s too difficult do I have a shot at e-commerce here on Shopify? I need like step-by-step from page one. I don’t even know what to sell
