Dear Bel,
I too had to give up what was not only my job, but my passion. I worked so hard to achieve and reach the position I had and it was a very hard thing to have to do. I had to give up not only the job, but another country, and another way of life so that I could care for Ken.
But my love, the relief when all the painful letting go was done, was enormous. Although there were new hurdles to climb over, at least I could concentrate properly on them.
Keep your chin up, Things will get easier for you.
