Thank you for posting your question here, I will try to answer it to the best of my abilities.
While you are looking for a potential donor, you can take some blood transfusions. This is not a permanent solution but at least it can buy you some time. You should ask your doctor to prescribe you with some antibiotics and antivirals as right now you are prone to infections.
You can also talk to your doctor and ask him options in bone marrow stimulating medication e.g epotein. If this works you wont need a bone marrow transplant
But if it doesnt then you have no choice but to consider going for a bone marrow transplant, how old are your children? They can act as donors for you.
I hope this answered your question.
