So sorry for everything that you have been through..you are going to be amazed on how many people understand here.
My son is bipolar,he has it under control right now,but believe me we went through hell for many many years.
I think that you should go back to the doctor,and let him know what is going on. It could very well be that your med dosage needs to be changed.
My personal opinion is that is normal,our bodies get used to the dosages so then it seems it is not as effective as it was before.
Also,are you in any type of therapy? you have been though so much,and they can also help you with methods on dealing with your husband.
Chronic Depression, Panic Attacks,Anxiety Attacks,Anorexia
Please remember,I am not a professional..I am just a person who is also fighting depression.
