Is my mom a case of Mental illness? What do you think? Any doctors in the house?

we feel our mother is a mental case for the following reasons:
1. Prefers "boyfriend" over her children, because she has said when her children grow up, they will leave her alone and atleast she has the "warmth of a man" next to her. (every guy she has been with has left her)
2. Constantly repheats herself over and over. She is at work and will call every 2 minutes asking if we did what she wanted and after we said yes.
3. COMPLETELY denies that something is wrong with her, & says she is perfectly normal, also says "we" are the crazy ones for pointing it out to her. She always feels she is correct, and never is wrong.
4. Emotionally abuses family members [i.e. i should have aborted you]
6. has so many clothes in her room she can't even sleep in it. everything is piled up to the point she cannot open her room door
7. constantly has her room door locked because she thinks someone is going to steal something
8. prefers to spend $$ on clothes instead of putting food on the table.

What can I do? I want to take her to a mental institute to have them check her out. My father took her about 15-20 years ago when i was a baby to have her checked out and they had said she did have some sort of chemical imbalance. I need help for her desperately. It has definetely affected our lives. please someone. thanks!

Think she needs help, but people with problems never see that they have problems it's always everyone else. They cannot see to forest for the trees. My feelings is she may never see her problems and all you can do is bear with her.
