OCD related. Illness like diabetes etc.

I suspect my wife having OCD tendencies. We have been married for 23 years. Initially I ignored it due to lack of awareness on OCD's but since it has started to affect our relationship I started reading materials on this and could relate her behavior to suspected OCD problem. Few e.g. I could think of I am listing it down. Always fear that something will happen to me or my daughter whenever we go out (office, tours, college etc.). Excessive time spent on cleaning things sometimes repeatedly, Aggressive behavior when things are not in place or temporarily out of place in house, very superstitious and ritualistic oriented, very impatient and short tempered etc. She is 45 , I am 49 & we have a daughter aged 20. Myself and my daughter has very little say in matters and to avoid confrontation we let her have things her way. She is very sharp, very observant. She is 5'2" ht and weighs 60 kgs and generally healthy. She takes 2.5mg BP tablet daily and has not other illness like diabetes etc.
