Can You Suggest Any Treatment for Breathing Problems and Lung Complications?

Question

I have been a victim of asthma ever since I was a small child. I have somehow lived through all the doctors saying that what I am suffering from is purely psychological. I have never been dependent on anybody and now I feel everything in life is taking its toll on me. My husband just died after a tough fight with cancer this year. All our friends have disappeared during our struggle with cancer. I do not have anybody with me now. Even my closest family is quite far away and I am not really close with them. I am now too sick to work and I had to sell my house to live. I am now being treated for despondency and I just do not see any point in living further suffering from severe breathing trouble and lung complications. I am feeling extremely desperate and exhausted all the time. I feel like committing suicide and would be extremely grateful if someone could suggest some alternative to get me out of the hell that I am living in. I am planning to buy a mobile Nebuliser as I feel that this may make things better for me. Please do get in touch with me if you can help me in any way.
