When was the hardest time of your life?

I am currently going through what seems to be the hardest time of my life... I am 26 years old, I had a good job, I had self confidence, I had happiness and always had such a smile on my face, I took a fun trip every 3 months... I was SO happy. I have a great husband and he loves me very much.... But things recently turned to the worst....... I dont want to get into details but something happened that completely changed my life and since then everything turned upside down. Sometimes I feel like its just over and I dont want to deal with it anymore. Ever since this happened to me people are rude and condescending to me. I was never treated like this before until this happened. I went through trauma and I would have expected people to understand and be nicer, not to treat me like this... This tramatic event in my life caused me to completely lose focus on life and I had to quit my job because I was so depressed. Many sleepness nights and constantly crying.. What can I do to help myself?
