What's wrong with me?

I am 26 and in my 10 years I have had a marriage breakdown and relationship break down. My ex husband loved gambling more. I know what went wrong they. But my recent ex boyfriend just had no excuse. I am not needy and I was literally Mary poppins but it just wast enough. His family hated me. He says they nothing wrong me I am just not right for him. Every where I turn I am not right for anyone. I am so depressed. I don't wanna leave the house anymore I don't wanna wear make up I don't eat I barely sleep. I just need to know whats wrong or if I am doing something wrong

Please no negatives but please be honest also...
