Why can't I post on my blog? Every week it's something else

I took a week off due to the frustrations of photos not posting, posts disappearing, no video access, robotitis - hits blindly and no one takes responsibility for loss of readership due to their not being able to comment or get updates. I am looking again at an error on a photo to upload. Would someone please tell me how to post and why are my past videos removed from my work? Especially with NO Youtube url access??? Other patches have had it for months. I am so sorry so many left.
