U4 suspicious thyroid nodule

Hi,

I desperately need some support. At the end of December I found a lump in my neck and went to the docs. They took bloods and referred me for an ultra sound. Blood tests showed high TSH 19.6 and low t4, compatible with primary hypothyroidism. Also have family history of hypothyroidism. Went for the US end of Jan and was told U4 single nodule, hypo echoic, solid and vascular 29mm. Since that day I have not been able to switch my brain off and am so scared of what is to come. I have a 9 month old baby. Referred on 2week wait and saw ENT. Went for FNA beginning of Feb which came back inconclusive. Went for core biopsy last week and now anxiously waiting results. I'm struggling to get through the days and can't stop over thinking.
