I also had difficulty showing my contribution and desperately needed my independence, struggled with asking for help and cried alone.
I dealt with this by creating a private facebook group of 'Angels'.
Women I trusted and I knew who would help me if I asked.
I was clear with my needs, I let them know what was happening and asked for space, but promised to ask when I was in need.
As things came up, I would tell the group.
They would decide who could help me best (lift to the hospital, help with housework etc) and they would schedule when to help.
I found it an easier way to ask,
less invasive to my privacy,
and they as a group, felt confident that they were helping as much as they could.
I am sorry you are going through this,
But the fact that you have already asked us for help, shows your inner strength.
And let those tears out, you are human, you will need the release, it's healthy to cry.
