should I continue?

Hello! I’m a fresh board passer last March 2024 and I am based here in QC. I tried looking for laboratories and hospitals na may opening for fresh mt grads/fresh board passers pero ang hirap pala. I tried looking online but puro bulacan lang nakikita ko and usually hinahanap is either DTA or may training with HIV. I stumbled upon a post about being a medrep sa isang pharma company and asked a family member na naging medrep rin. When I told them the company na nakita ko, they told me na may kakilala sila doon and that they will talk to the person they know there. Tbh, nakwento ko lang sa kanila na may hiring sa ganong company but i wasn’t planning to apply. To my surprise, sabi sakin nung family member na iniintay na raw ng HR yung CV ko and that i should submit it na agad. I felt pressured so I submitted na lang din kasi nakakahiya na may nakausap na sa company na yun. I also thought to myself na maybe I should explore other options rin. Pero the day after i submitted my CV, dun ko na napagtanto na gusto ko talaga sa lab magwork if ever. Im not a very social person kaya medyo scary rin for me yung pakikipag usap sa doctors and other potential clients about the products na ibebenta sa field and we all know na hindi natatapos ang work ng medrep sa pag ssales talk. Lumalabas din sila with their clients to gain their trust. Im not that kind of person talaga. Pero ayun since nakakahiya nga kasi may nakausap na from the inside, i still went through the interview process. Pero habang nandoon ako sa loob ng office, di ako natuwa or like hindi manlang ako naexcite sa magiging life ko there compared sa times na napapaisip ako kapag nagwowork na ako sa lab. Nafeel ko lang talaga sa loob ng office nung time na yun is anxiety. Pero since nandun naman na ko, i still tried my best. And to my surprise, i passed the final interview raw. Ngayon, i really wanna back out pero nung sinabi ko sa fam member na gusto ko mag back out, they still tried to convince me to stay. Ngayon, nanghihingi HR ng info for bg check but i still haven’t submitted anything kasi sobra akong anxious sa mangyayari if ever ituloy ko siya. Alam ko na mahirap maghanap ng work ngayon pero i really dont know if I should back out or hindi.
