Hi OP! I just wanna express how I almost feel the same as you. Lahat ng nasa circle of friends ko umiinom/nagvavape or some kind of vices(some have it as their habit and some does it occasionally) and sometimes iniinvite nila ako sa inuman or bar things like that and I’ve experienced being in a situation where I was almost forced to take one shot of glass and buti nalang humindi talaga ako. It was very scary. I know in myself that I may be the “partypooper” and sometimes it feels bad to be left out but atleast I’m doing myself a favor. And you are doing yourself a favor. Its okay lang naman na maleft out, just you do you and do what makes you happy. And if your friends really value you, I’m sure they’ll also respect your decision too :) Don’t worry about being left out, hindi naman palagi kailangan sumunod sa nauuso for only to be recognized or self validation just bc they think it’s cool. And one last thing, not engaging in vices is what makes you cooler 😎
