Hi Mago 
I am so sorry to hear about everything going on in your life. You are so strong and resilient for still going on and your posting here just shows you’ve got a little more fight in you. 
If you can, maybe you consider asking your doctor for medicine or try and start therapy. Those can be life saving, and changing. 
When I have suicidal thoughts and ideations, it’s usually because I want relief, not because I want to die, so please try to get some relief in any way possible. I am so sorry your family and husband aren’t being supportive. Your husband should be standing with you through this and it is his failure that he is not taking care of the person he pledged to stay with in health and in sickness. Don’t blame yourself because they can’t see what is going on. You are entitled to empathy and care and I hope you find it. 
You’re so brave. Please keep going 
 
 You can look for facebook groups, too maybe, or find chat rooms for better ways to chat with people about this. That has always been where I found the people that would weather the darkest nights with me. 
Feel free to send me a PM ^.^
