Can someone just listen please...

I live with PTSD, severe depression/anxiety, and ADD. My husband (he's a vet) has PTSD along with depression. We've been married for 2 years. Our first 7 months of being married we miscarried with our son at 21 weeks, his grandfather past and he tried to commit suicide twice. I am an optimistic person but I am only 23 and 2 years later I am still making sure he's okay. I'm still trying to make sure he has what he needs to keep pushing what happend to us really broke him and when I try to express myself and just let my cup run I feel like he doesnt understand that I am tired and overwhelmed with emotion and stress. Its hard to explain to him that I need him to take care of me emotionally and not just physically/financially as well. I just need to vent. I just need support from my husband with out feeling like an ass for expressing how I am feeling. I use to go to a therapist and take antidepressants but had to stop because of insurance reasons. I want to join the airforce so I have to be off any meds to join. I feel like we're only harming each other but I love him so much and I know he loves me but I don't know if my marriage is going to make it. I dont know what to do.
