Low BP need suggestions. Be worry about.

Hello doctors I was having high BP issues (BP usually 145/90 160/95 155/90 etc) so my doctor started mild dose of olmezest 10 earlier i was taking olmezest 20 but as it was making my BP low so doctor reduced the dose. It's been 4-5 months I am on this medication. I have observed specially during afternoon my BP gets low while I am resting like 115/73 104/68 and sometimes even 102/74 99/73 like that as well. And plus rate is also 73,82, 76 etc. I am not sure if it's too low I need to be worry or not as i am overthinker. I was suffering from anxiety as well which have come down by god's grace. When the BP is low sometimes i do feel light headed not always. Rest whenever i have checked morning/evenings it's always in healthy range. I am scared of all these heart issues and the news what they show on TV that all young people are dying due to heart issues. It's makes me anxious and scared so I always think that my heart should be healthy. Please suggest if anything needs to be worry about.
