Yeah, there's not much anyone can do about people mocking you or anything like that. However, my advice is that there's always going to be some stuck-up people on the internet who think it's their job to be the biggest pain possible to anyone. One of my tips regarding those people is to just ignore them and only listen to the people who post with good intentions.
Don't worry though, because there's a lot of mature members here who will help out. Maybe if your questions still don't get answered in their threads or in chat, you could PM one of the mods asking how, because they will likely either know how or know who to direct you to if they don't. Also, you could always try coming into chat at different times and asking, because there's always different people in chat as other people leave and join.
