That said what I feel is the very basis of self love is missing for you darlin. It all starts there. I know you are not connecting with yourself and feeling love and care for yourself and that is what is reflecting back to you from your world. It's possible you are even feel self hate right now. This all makes me feel sad for you.
First step to try.. radical self love.. as others have said. Clean your room. Make it your sanctuary. Candles, things you love around you. Start making gratitude list about what you like about yourself, what are you good at what are your strengths? recognise that you have lots to offer... Re read the books you have, pamper yourself, let yourself know YOU DESERVE IT!!!
This is only a first step, but I recommend doing this. Even for one day and come back on here and tell us how you feel about yourself. Not what anyone did to you. Just how you feel about you!!!
I wish you luck with it, I am willing to listen to your journey out of this place to REAL SELF LOVE it will be a wonderful journey for you!
