I am in tears and I'm a grown a$$ man

I came to my site today only to find that my site is in complete shambles.  Sections now have spacing between them that never existed before.  Images have shifted sizes for no apparent reason and the mobile site OMGod, there is spacing issues EVERYWHERE where they were none before, code blocks are taking up rows.  I was at the final end and ready to launch and now I can only sit here at 2:30 AM in the morning and feeling nothing but hurt, pain and frustration.  I have removed all the CSS codes to see if something was randomly in there and still the issues persist.  The only thing that seems to cure the spacing issue at least is that I have to recreate the section all over again, but then it messes right back up as soon as I add a video or an image back in and the mobile site is now just a waste of space.    This just can't be happening.  I have worked tirelessly on this site only to come back and find it's now a piece of sh*t.  SS you have done a number on me and I hate you for life!  I wish I had chose a better service.
