Don't know why you are being tested still. I am praying daily for your recovery. I went through this scenario 14 years ago but had quintuple bypass and no blood clot. I really did not have much to forewarn me. It just developed and suddenly I had to deal with. Well that procedure saved my life and my prayer is that the Lord will lead you back to full strength. He's not done with you yet. Still needs you as part of his earthly choir.
Here's something I wrote a while back. Hope you can take strength and encouragement from it.
