Can life get any worse?

Every day is a struggle. It seems like whenever u walk forwards you end up taking 10 steps back.
Time seems to stand still whilst everything spins in circles around u, and u feel like your head can't catch up. 
A feeling of helplessness and dread overwhelms you. Everything feels distant to you.  You don't want to be around the fun things anymore because they remind you of the sad times. 

You say to yourself is life a waste of time when the things you love have gone? And the stresses in your life seem to gather and smother you,  making you feel vulnerable and alone.  

Depression is hard to shake.  It won't just go away and even with time sometimes it gets worse.  Ever since my son died things haven't been the same for me, mentally.  And now on top of that having to take care and nurse a paraplegic dog,  who cannot pee or poop for herself and that is taking up almost all of my life.  I'm not complaining that I have to do it because I would never put her down because she could not walk,  but when you have other stresses in your life that pile on top of something that you already have to do it becomes harder and my mood changes,  my attitude towards life changes.  My life has been turned upside down, and even if I didn't have her,  I would still feel the same.
