Loneliness Support Group
Loneliness is an emotional state in which a person experiences a powerful feeling of emptiness and isolation. Loneliness is more than the feeling of wanting company or wanting to do something with another person. Loneliness is a feeling of being cut off, disconnected and alienated from other people. The lonely person may find it difficult or even impossible to have any...

Often we are taught to isolate ourselves, try to pretend things are ok, and not bother anyone with our problems.....but all of that is not so good.
Like you, I have been through alot in my life. Over time, different circumstances did lead me to counseling (therapy) a few times and this has helped me to finally understand some of this. Now, I try very hard to see why people are the way they are.
If you look at your parents, you may see especially in your mom's case....she never felt wanted or loved . Often these patterns continue through generations.....they are not capable to love and nurture us because they never learned how to. I would lay odds that your father (and his as well) was brought up in a very angry household, full of blame and disrespect...so that is what he learned.
IT WAS NOT BECAUSE OF ANYTHING YOU SAID OR DID AS A CHILD THAT YOU WERETREATED AS YOU WERE.......but because that is all they were capable to give.
You should know YOU ARE NOT ALONE. There are so very many of us who continue to have times we feel this way all our lives. For me it has helped to reach out and share (and learn) from others. I believe that every person I have come to chat with has brought me a step further toward that healthier, happier life we all want.
So kiss that precious little baby, hug that husband and hold them tight. Know that you are a truly special and lovable person who has been blessed and has a chance to begin new traditions and break this cycle of abuse. My thoughts and prayers are with you all.
PS. Turtles may have a point too. May also be post partum depression making this worse for you.
Hugs,sympathy,and empathy
