Happy 16th dear! 
Wow, it really sounds like you're stressed out! Working on a comic can be really tough and really intimidating. I know when we first started we really had no clue what we were doing - but we figured it out.
Give yourself some time to work on your comic well before you start posting. I know you want to get it up and running soon, but having a big stack of comics done before you start makes your job sooooo much easier down the line, and totally less stresseful. You still have to work on new pages, but you have more time to do it and improve too!
Keep us updated as you go along! I'm interested to see how you go about it!
