What Is Wrong With Me That I Will “give In Or Give Up” Even If I’m Neglecting Or Harming Myself?

What is wrong with me that I will “give in or give up” even if I’m neglecting or harming myself?
I’ve been doing this all my life, almost like I’ve had this incurable disease of hopelessness that I’ll keep until I die. Here are some examples…
1 – When I was 21, I dropped out of college to be a single mom (wasn’t the plan). I signed over a house, out of guilt, that was left to me by my mother to a family member who had been living in it – but they knew years in advance about the situation. So, I didn’t have a home for me and my child and just lived with other people.
2 – I had an opportunity to live independently through a federal housing program, but didn’t show up for my appointment for it because my mom told me if I took it that I would be looked down upon by family.
3 – A boyfriend moved into my apartment..then moved his kids in and all I did was complain to family and friends on the phone. I finally moved out and found a more economical place, but it was too small. The boyfriend agreed to put the lease in his name before I left, he never did, so now I have a debt on my credit report for the apartment and the damage he and his kids did. I got back with boyfriend later who I let use my car occasionally – and he had no drivers license. Every time he used it, I would go through periods of anxiety hoping he wouldn’t be stopped by the police.
4 – I had a fiance who moved into MY home and abused me. I didn’t press charges against him, I just ran and became jobless and homeless, never defending myself. He’s currently incarcerated, but not by my doing.
5 – I let an old friend pay for a plane ticket to fly and see him when I knew I didn’t want to go because I didn’t trust him. I wound up flying back earlier than planned – with a vaginal infection and emotional scars.
6 – A family member died, left me a few dollars, and her son tried to manipulate me into sending him half – to pay for her funeral expenses. Of course I told him yes, knowing he doesn’t need it, because you see, I’m homeless, jobless and destitute, not him.
7 – I always say yes when I really want to say no…but I don’t feel it’s right to say no even when it interferes with my life. And then I look at other people and think how selfish they are.
What is wrong with me? All I know is…I’m very drained and tired and disappointed with myself. I often wonder how disappointed God must be with me.
