Your anger, frustration and depression is justified. You've lost your business, home, step son, husband and dealing with financial problems. I can't identify with any of this but when I first became depressed about
a year ago I was home all day, doing nothing, no motivation, not wanting to exist, not wanting to see people which is what your currently going through. I'm doing better so it can get better.
You really need someone to talk to like a Therapist plus see a Psychiatrist for the depression. I don't take medication but I'm certainly not against it if it helps. Seeing both a Therapist and Psychiatrist is the first step in healing. If you were able to run a business for 13 years you certainly have the skills for the workplace when you're better both mentally and physically helping someone else run their business.
You don't want anyone bothering you so you broke contact with your parents. These are the two people in your life that at some point down the road you may need.
You can't give up hope and you must get better for yourself and your daughter who needs you. Do whatever it takes to get better. I know that it's not easy but it can be done.
No matter how bad it is there are many out there who are worst off. You still have a home, family and some income although it may not be enough.
You're much too young to give up. You have many years ahead and you can no longer go on living the life you're living. Get Help and reconnect with your parents.
Whenever I hear stories like yours it makes me appreciate all that I have. I'm dealing with depression but I'm functioning. Yesterday, I didn't have a great day but I thought about those who are worst off and it helped.
I hope you post again and remain active on HealingWell.
