I'm very scared

I’m 40 and I got this diagnosis

initial histopathological diagnosis: melanoma in situ VS.
melanoma t1a
Antibodies: KI67, HMB 45
results:
KI67 positive in approximately 15% of the melanocytic proliferation nuclei
HMB45 positive intraepidermal melanocytic proliferation
size lesions 5mm, depth 0.6mm
final diagnosis: melanoma in situ radial growth phase , negative margins (tis NxMx)

is melanoma in situ or t1a?

Hi you, have you been seeing someone who you can talk to about all these stuff? Hope you´ll get the help and support you need.
