hmm...masyado nang late ang reply nato para sa post mo..nyahaha..pero i'd still want you to know my opinion regarding your problem.
Firstly, si Daddy mo suicidal. I think it's not yet time para iwanan mo sya, you're not mature enough din para iwana sya and stand on your own feet/foot/toes whatever. So for now,stay with him, spend time with him and your step mom.
second, si Mama mo, kinocontact ka. wala namang problema dun. ikaw ang problema cause you're trying to avoid her. Kahit alam mo or hindi ang reason ng paghihiwalay nila, that shouldn't cloud your relationship with her. Alm ko, right now ang step mom mo ang "the best' mom for you. but give you're mother a chance. communication lang naman for now ang necessary. Ngayon, tungkol dun sa green card, ask your mom if she could give you some time, until you're legal, or better yet until mag 20 ka to decide. kung practical ka, you can use that green card someday.
lastly, teenager kapa lang ngayon right? teenagers are usually sensitive pag mai ganitong problema, and they base their decision sa emotions nila, not that it's wrong. minsan kasi dahil sa emotion nagiging mali ang desisyon natin. galit ka ngayon sa mama mo, but please don't decide base on that bitterness, ang shallow ng reason na yan.
So advice ko lang, for the days to come,you have to be strong. Madaming information silang ibibigay basta sayo. kung pano nauwi sa ganyan ang family nyo, kung bakit nag desisyon sila ng ganun. What you should do is just gather those information. ipunin mo muna, don't decide just yet, don't choose sides. you need to think it thoroughly kasi you need to decide not just for your parent's sake, but for your own sake as well. I gather mo lang ang informations na ibibigay nila, keep it until the right time comes na kailangan mo na talagang mag desisyon.
Consider your emotions, but don't let it cloud your thoughts.
