^Sis, alam kong this may be easier said than done, but you have to trust that things will work out. For now, at age sixteen, your self-esteem is still forming and you need a lot of reassurance that you are lovable. So I think you don't really need a bf yet (at that age, a bf is an unhealthy distraction from your studies), what you crave is to get feedback that somebody finds you attractive and lovable. Sabi mo random guys whistle at you in the malls/streets so take that as a sign that yes, you are beautiful.
Sa ngayon sis, focus your attention on your strengths: matalino ka, magaling mag-alaga, friendly, etc etc. Your physical beauty -- darating ang araw na you can afford to take better care of yourself, when you're working. Getting braces, hair treatments, facials, those kinds of things will help you blossom into a prettier version of yourself. For now, I hope you can stop na magkunwari sa friends na may bf ka, kasi it won't give you peace of mind knowing that your white lies can be discovered anytime. And that will put you in an even less attractive light.
I really hope you won't get into a relationship motivated by insecurity. I had a friend who was fond of phonepals/textmates whom she ended up having FUBU relationships with. That's the kind of thing intelligent people do just to feel validated and loved, even though it's not the real kind of love. So don't fall into that trap. Make sure that when you decide to enter a relationship, you feel whole. And you feel happy about yourself. And you can start that process now, by addressing the things about you that you have control over. And then the rest... leave it up to God. I don't know if you believe in Him, but my faith helped me through tough times when I was struggling with self-esteem issues. I didn't end up sleeping around just to prove that I'm attractive, which sadly some girls do and are still doing.
Because I wasn't in a hurry and waited on God's guidance, I met the man that I would marry at age 26. That's 10 years older than your age now. Now imagine you have a bf this early, you would most probably be pressured to give in to his sexual advances before you reach the age of 20. Then because you started out too young he would feel like hindi pa sya sawa sa pagka-binata nya and would start flirting with other girls, you break up. Pero by this time nabigay mo na ang virginity mo. And there are men out there who will be ok with that, meron ding hindi. So you cut your chances at finding The One by the percentage of guys who want a virgin. Ilang percent ba yun, 50%? 30%?
You get the picture?
While you're studying focus on your studies. Lovelife will come later, when you've had a chance to love yourself muna, and discover what you want in a partner.
