Dear ONM, what ever it is that is going on for you , whatever you want to call it, it is causing you some problems. How you feel in yourself, how you are feeling toward your family and how you are relating to them. It is great that you have told your husband how you are going. He is right on the money, it is worth getting some help.
There is no reason to feel embarrassed, you are not alone.
You have already taken the first step in getting some help by reaching out here in this forum. Well done! Many forum members have posted at one time or another about feeling embarrassed or worried about seeking help. They are common concerns people have. Remember anyone you go and see will keep things confidential.
Make an appointment with your GP- that is a great next step. With the right help things don't have to stay the way they feel now, they will improve.
Let us know how you go,
