High B12, Ferritin, and Platelets with weight loss, dizzy spells

I have been struggling with rapid weight loss. I was 173 at the end of 07/2023. I am now under 140. I have had a lot of change and stress in my life so I attributed it to that. When it continued I went to the doctor 12/20 regarding my concern and had labs done. All of which came back normal besides low Vitamin D. Well the loss didn’t stop and I have lost 10-15 pounds since that appointment. I went back today for another concern with a different doctor and brought up that I was still concerned about the weight loss. She redid some labs and added new ones. The abnormal results are as follows

Ferritin 216
B12 1,165
Platelets 422

I am highly concerned and scared and worried.
In December these were my results for those:
Ferritin: 83
B12: 384
Platelets: 306

I have been hyperfixated and worried about my weight and everyone said it’s the stress you’re okay blah blah.
Now I am in a rabbit hole and must wait for the doctor to call tomorrow. Everything seems to point to either liver disease, kidney disease, or cancers.

I also had to have my BP checked 6 times as I expressed I’ve had episodes of standing and vision goes black, dizzy, and immediately have to sit so I was concerned about orthostatic hypotension (I am an LVN). My BP recheck was lower than when I arrived, heart rate sitting to standing 83 to 111. Then they had me drink water and recheck and it went to 81/63. More water and finally stabilized.

I have always had back pain and used to visit chiropractor regularly. I haven’t gone in years and it has been very painful lately.

I am trying to give a full picture. I’m just hoping for some information and support as I’m very stressed about what this could mean 🙁

Thank you all
