I need help

I am 27 years old. When I was 9 years old I witnessed my best friend and his mother's death, their plane crashed and I was supposed to be on the plane with them, then I was married at 19 to a VERY abusive man, finally divorced him at 21. At 22 I joined the army and was deployed.While on active duty, they diagnosed me with PTSD, Depression and Anxiety and mild OCD. Lately, I have been having flashbacks from the plane crash, due to the fact that I have a trip coming up, I have been very busy and finances are strained so my Depression is kicking in. My husband has also been deployed 3 times and between the two of us with the PTSD and my flashbacks I feel like I am COMPLETELY losing it. If anybody can help me with ideas on how to manage my issues with my PTSD, Depression and anxiety, please tell me. I have seen a therapist and all he did was give me a TON of pills and I hate taking them.
