hi! As someone who has gone through, and is still going throuh depression, I know how it can be. I have flown off the handle at times, and also been withdrawn to the extent of alienating my husband and others. The good news is that you recognize what is going on....and you are willing to get help. Congratulate yourself!!!! Don;t put off getting help......do it YESTERDAY!!!!! And, it is never too late. She is still there. You are still there. You need to work on yourself. You need to get help for YOURSELF. Don;t just get help because you are afraid to lose her. It will never work this way. However, she will need to get some help somehow,too, with you, to know what you are going through, what exactly depression does to a person, and learn some coping skills of her own. It is just like you have a physical disease...(cancer, diabetes, etc)...you have to get treatment foryourself, but she also has to understand you, the treatment, and how she can cope with herself and you in the meantime.
For me, I didn;t really understand depression and what was happening to me. I just wanted husband to go to counseling with me to work on our own problems (ome which were contributing to the depression in the first place), but he never wanted to go. And, I didn;t go by myself...,,,wanting him to help me, help us, etc....Well, he never understood the depression,and I should have just gone on my own (talk therapy,,,I didn;t want pills)....well, long story short, my husband and I are no longer together...and now I am more depressed!!!!!!!! It wasn't only the depression that split us up, but also some of his own behaviors as well...........
So........JUST DO IT. Get help YESTERDAY!
good Luck.
