My husband is 17 years older than I am. He was recently diagnosed with mild cognitive impairment. He also has type 2 diabetes. He has become very mean and grouchy towards me. Blames me for everything. I am his only caregiver and I work full-time. Any suggestions on trying to deal with mood swings or MCI would be great!
Has your husband's doctor put him on an anti-depressant and/or an anti-anxiety medication? If not you might want to discuss these medications with his doctor.
The main caregiver always gets the brunt of the bad moods and ill temper. Everything gets taken out on the caregiver. You can try to discuss this with your husband but he's not liable to understand.
There are a few things you can do to maybe make things easier. Don't correct him. If he's getting the date wrong or is remembering something wrong don't point it out to him. If he believes something that you know is not true don't disagree with him, just be noncommittal and let it go.
Is he safe at home alone while you're at work? You might want to begin thinking about in-home help for when you'll need it.
Let friends and family know about your husband's condition. You may have to call on them for support or respite so you don't wear yourself out caring for him.
And come back here and vent as much as you need to.
