Another Bump in the Road

Lately, I've done more reflecting about life, and what I expect from it.  Basically, I want to be content, and live life to the fullest, but these past few years have been very discouraging, which is why I joined DS.  I've dealt with a number of issues which include, domestic violence, family estrangement, mom's dementia, and my own health concerns.   
I recently went for an eye exam, and was told that I need to have laser surgery.  I don't have any other options because my vision is compromised.  I'm trying my best not to freak out....but it's overwhelming.  It seems like a never ending battle, in which I will ultimately lose.
I'm also experiencing more PTSD symptoms as a result of an abusive relationship.  It's become increasingly difficult to watch the daily news because of the frequency of domestic violence reports.  It's become an emotional nightmare....so I try to limit my viewing.  Sometimes, I feel like a "lost sheep" who's struggling to comprehend everything.  I have a good support system, but I still feel all alone, and miserable.
