Time to start Meds

well just been my 3 month appointment  with my specialist, and went in so confident that all were fine, and did not expect to be told that she recomends that i start treatment , as my CD4 is 345 and VL 360,000 , she wants to start me on Atripla, and I have to go back in a month when i get my head round it all, I knew that time would come, but just were not prepared for it when i were told, My last counts 3 months ago were 475 and 60,000 vl but she says it works on the precentage as well over the 2 years i have been seeing her since being diagnosed . just now feel lost and dont know what to feel anymore,
