First thing --- It seems you have developed Some Neurological Disease , Since you have not taken name so I can not make it out (Most diseases are rare and beyond scope of even understanding by common MBBS Dr, They max. if at all knows the name or some time they don't know that name too)
Second thing --- Sorry but to be bold , some where I too had neurological complication , and of your age only. This disease at this age don't go and you have to adjust with it for remaining life , And it becomes very trouble some for anyone to understand even your close relative etc. So instead of supporting they keep on criticizing or talking or explanning philosophy of life without even understanding scientific basic. And it creates lot stress. And problem in relationship.
Third thing --- As time passess you understand limitation (I don't know about you but in my case some limitation are there for lifelong now) , So to move ahead and to take new type of proffession, developing new skills within the scope of your limit is and should be goal for life now. I too had to sacrifice some thing which I never had thought of , but took decission with reality I have to live better I move my proffession , change work, try to earn from different skilss which may be even not allowing you to go out of house etc. I think it is called Occupational thearphy who guide patient to cope up with limitation etc. This is what they had recommended me once.
Fourth -- Once you are bit ok ,or depends upon percentage of efficiency then you may be able to regain confidence and others too may regain confidence ( This achivement takes lot time , it is not easy that if you decide and do it today only or withing 1 month , it will take time)
Fifth -- As this is your first year , if time passes you may face more stress and tension but you have to face them there are many people with rare disease and they have social group on facebook etc where you can share thoughts and understand progress of the disease and coping up ability ( When I suffered first case in medical journal was published in India , Now you understand what you can expect , even Dr. where donkey who did not understand iota of disease)
Sixth --- When you say your wife age 33 , She or your in law may be practically thinking about next 30-40 years for her and be bold enough the way the people reject boy or girl at looking at time of marriage so similarly they have entered phase and taken bold decission to leave you some where and you need to accept the reality. More you pressure for her to stay more she will harass you.
Seventh -- There is no place for one sided love, Divorce is common and they may have made mind to leave you ,in their sub conscious mind. So be bold and accept reality of life and take decission
Eight ---- I am not good in personal issue because whenever i say anything on personal issue regarding matrimonial i only get negative effect because it is less about law and more about philosophy how you look at it.
Ninth --- I feel you talk to with your spouse and in laws about future of marriage with cool mind. If she says or in law feel they should not continue with this relationship of marriage give them permission that you are ready for Divorce with mutual concent and all cases they should withdraw You decide with help of friends and proffessional how to live remaining life. There will be some one who can undetstand you better and your situation
Tenth --- Sticking to relationship where one person have decided to exit is more harassement because that person no matter what good you do for her she will do things against you and leave you and mentally harass you.
This world is practical accept it . This is what I can tell as friend to you.
God has given you acid test may be some thing which you never thought God has planned for you some thing more better. Have faith in him
