My mom has ms so I don't really know how you feel. You sound like my dad though my mom was diagnosed in 2002 and my dad was deployed. What a thing to home to right? I have 2 brothers and 2 sisters and my dad is still active in the military and married to my mom. I know it's hard sometimes and I also know that it will never get easier. My dad works, cleans, cooks, attends every event us my siblings and I. You get tired but when you love some one it's worth it right? I just recently got married and my dad's advice to me was there always needs to be 200% in a marriage. I agreed and said yes 100 from me and 100 from him. When he told me I was wrong I was confused marriage is suppose to be fair isn't it? He then told me there would be times when I can only give 40% therefore my husband would have to give 160% and vice versa. Because marriage isn't about what's fair it's about caring enough for the other person to give them all you have and more. Maybe nows your time to give 160%.
