Please help Becky

Found out this week my 5 year old boxer Becky, she is the white dog with the big smile, has a blood disease and her only chance involves several blood transfusions and steroids. The pandemic has cost me a 10% paycut on my main job, and eliminated my side job driving for Uber, as business has dried up, and also, I am in a high risk category, and am quarantining. All in all I my income has taken a 40% cut, and I have been staying afloat using credit cards. Yesterday alone cost me $1800.  I had initially opted for euthanasia, as I knew I didn't have the money for all the treatment she will need, but at the last moment sitting with her, I just couldn't do it. The night before my other dog, Snoop had a seizure and stopped breathing. I know his time is just about up, but I just can't face losing them both  at the same time. Please help if you can. Becky is only 5 and has previously been very healthy and strong. With your help she may be able to have several happy years of life. Thank you for any help you can offer.
