I think it is so much easier asking/fighting for something on behalf of someone else. My first hubby had MS and I fought many a battle on his behalf for things I thought he deserved. I also worked with adults with LD and the elderly and again, thought nothing of asking for something on their behalf. But when I became ill and had to give up work, my confidence just flew out the door and I didn't have a clue. I always feel as though I am having to go, cap in hand, for anything I need to help me. It's as though we are always thinking, there are other folk worse off than us that could use this money/help, whatever. It's horrible, but you are not on your own. I can only suggest trying a bit of mindfulness, instead of thinking you may get a rebuff, try and think how you deserve whatever it is you need/want. Think that's how it's meant to work.
