Hi @CarolC
Welcome to the forums & thankyou for sharing part of your story. I hope you can find some support and maybe answers here.
I have lived with depression for decades now. I cannot remember how life would be without it. Thankfully, medications have had positive effects for me, at times I still experience episodes of being flat, as you describe it.
It has been a case of trial & error to figure out the right treatment & dosage. At different times in my life I have found different meds more suitable, as well as periods of none at all.
It sounds as though you are feeling in a lonely place at the moment. The man you married has withdrawn & excluded you in his recovery in some ways. I'm sorry you are going through this.
I was wondering if your husband is taking anti depressant type medication, & if not would this be something he is open to trying?
Does he have any hobbies or interests that you could research for him & encourage him to join eg. The men's shed.
I can't tell you how long this will last, or if he will return to his old self again one day. I can understand how hurtful it must be for you. Try to support him as much as you feel comfortable. It's important to also focus on your own needs, by doing things that support your own happiness, perhaps in time, hopefully he will come around.
I'm not sure if any of this is helpful. My best advice would be to take care of you!
