Hi, Scallywag123, and welcome to Psych Central!
I'm so sorry to hear about your husband. I'm sure you did the best you could under the circumstances. I'm amazed you were able to solely look after him for so long. He was blessed to have you. We're only human, so we must rest and get a break somehow or we'll snap.
The best people to be supportive of you are other widows, and I'm sure we have some here. Please make yourself at home. You'll have some new friends here, including me.
Again, welcome!
