Yes, child abuse can affect you 22 yrs later! It can affect you at any time.
I noticed that you mentioned that you had been to outpatient therapy...did it help some?
If you have unresolved issues in the past, the mind has a funny way of making you deal with it; be it depression, or constantly being sick. Stress does that too....the stress from your past.
Your not wanting your husband to touch you is very understandable, because that seems to trigger memories for you. Has it always been this way? I hope not...because it is better to deal than to bury.
What is happening in your life now, and probably since you were 17 years old, has been the aftermath of what your mother did. When emotions, memories etc are not dealt with in an efficient manner, all sorts of other problems arise.
Seek counseling to deal with these memories, and try to talk to your mother about them too, if that is possible. A big thing, is that we have to say what's needed to be said, if it is eating away at us. If it is possible, tell your mother how you felt, etc. If you can't do this, then start with therapy and then try to do it (I am assuming your mother is still alive, if she isn't, sorry and please let me know) at a later time, when you feel comfortable with it.
Another thing, don't shut your husband out, I hope that you talk to him about how you are feeling. Communication is the biggest support that one can have. I say this about communication, because my husband has been through similar in his childhood, and he is not communicating with me....which is causing a huge strain....and loss of patience.
Hope that this has helped some, keep us posted.
