One thing that is worth knowing is that you are loved and worth so much to so many people. Be that your own kids and family and friends. If it was me I would get out and pen and some paper. Write a letter to my mum and tell her exactly how she made me feel over all those years. I am not suggesting you send her the letter. Just write everything in that letter. How you feel today, looking back on your life. Once you are done, try to answer your own letter, as if you were your own mother. No easy task at all. Can be emotional to do this exercise. But that is the whole idea. When done with both letters take them out back and burn them. Letting go of the past. I would also try and find self loving affirmations. There are loads on the net. Write them on sticky paper. Stick them about your house. So no matter what room you go into you will see positive words. Say them out. Make them part of your life. They will become part of your subconscious mind. It will be another step forwards.
