I have Agoraphobia, CPTSD and chronic fatigue. All of these things have been diagnosed (not self diagnosis).
I have struggled with the above for over 10 years.
At my worst, I left the house around 3 times in 12 months.
During that time I was a "housewife". I assumed the complete running of the household whilst DH worked full time. I would never, ever have expected him to do any housework.
If I was especially tired he would suggest getting a takeaway and we did keep some good quality ready meals in the freezer, but otherwise I cooked every meal.
I self managed. I had a schedule with cleaning days. It really isn't a huge task if you choose one chore for each day of the week and do a bit each day.
You sound a bit stuck in a victim mentality which I 100% understand, believe me.
But you need to step outside that if you are going to have a functioning marriage and also heal yourself.
I had a lot of compassion for my DH whilst I was at the height of my sickness. It was emotionally and mentally draining for him to have a wife that was going through this and it was terrifying for him because unlike a broken leg, there was no end date to hope for.
I still struggle with all of those things, but I have gradually improved and whilst I don't do as much as the average person, I really push myself to live life to the fullest for myself and my family.
Invisible illnesses are the worst because you will face mocking comments and people thinking you are gaming the system or just plain lazy. I KNOW this isn't the case. But I also know that once you strengthen yourself mentally and change your outlook, you can get much more done.
If I leave the house I still need to rest or sleep when I get home. I am emotionally and physically exhausted. Sometimes I sit in the bath and cry with how drained I feel... But the joy on my DHs face as we hold hands and go out together is worth it.
Sometimes I don't have the energy to cook dinner and clean the bathroom, but then I think to myself that both my DH and I deserve a clean environment and food to nourish us.
Try to reframe your annoyance at each task and instead be so proud of yourself when you have completed it. I reward myself a lot and find that dopamine helps me raise my energy levels.
Whether it's saving a new book for after I have done meal prep or a little bag of sweets and a cup of tea for after cleaning, it really does make me smile and find joy in the satisfaction of achieving simple things.
You can learn to find a new normal and function to the best of your ability. You may struggle with these things forever, I know I will, but I also know we only have one life to live so we can't afford to waste it.
