I have thought about saving up money and disappearing for a while but I have a kid. I'm really ashamed to feel this way but the pull is becoming irresistible.
Why do you want to run away from everything?
It is fucking impossible to save up enough money for this getaway. I tried this before but of course something always happened.
Even if it was possible to do so, you shouldn't be planning on abandoning your children.  You are expected to care for and to raise your child.  You should be saving up money for the future and to help you care for your child more successfully.
It is so frustrating when people do not get my perspective. I am tired of feeling trapped.
You should try opening up to your family and others to share your pain. Running away won't solve anything and if you need some time alone, then let your family know about it. They want the best for you and will help you get better.
