I am sorry that you are having a tough time. I can relate.
Not having a husband or friends or having a bad job.... these are struggles most of us share... I wish i had a solution for you but I don’t. all I can say is that you and you are the only one who can make a change about the things that bring you down. It is important to have good people in your life and I hope you can find them.
May be you are having a bad day and tomorrow you will feel better?
May be it would be beneficial looking at the positives in your life? I am sure you do have it... we all do. For instance, each morning I start the day with watching the sunrise while having coffee. This is my guaranteed positive each day. Even all else fails, I got my sunrise and coffee.
So what is your positive? Please try to find them.
