MDS diagnosis with DDX41 Germline and Somatic

For the last 6 months I've been going to a Hematologist to determine the cause of my low WBC, low platelet count and low B12 level (153) and a history of binge drinking (I've since stopped drinking). Normal Hemoglobin of 14.3. Also been on Clonazepam and Lorazepam for my anxiety for the last 22 years.

After 4 months of weekly B12 injections, my B12 came up into the 500 range, and my MMA level is in the normal. I was also prescribed Folate supplements along with two BMB 3 months apart.

After 6 months, all my numbers stayed the same: WBC 1.9, ANC 1.1 Platelets 192
My Hematologist sent me to an MDS specialist who determined that I have a low grade MDS with a DDX41 variant, both hereditary and somatic.

Recommendation is to wait till my Platelet count goes below 50 or my Hemoglobin level goes below 10 then go directly to a Stem Cell Transplant.

I am scared beyond belief. I am a 61-year-old white male. They could not give me a prognosis on the success of this procedure, or how they define success (6-months, 6-years, etc....).

The plan is I would have this procedure done before I need chemo, stay in the hospital for 1-month, then for 3-months on an outpatient basis go to the hospital twice a week. With a 1-year best case recovery.

Has anyone gone through something similar to this or can give me any information about this? Please any input would be greatly appreciated.
