Hi and Welcome.
I know the type of family, mine is very much the same in regards to God, christianity etc. i fought that battle for many years and realized i didnt need to fight anything (i was only fighting and hurting myself and others), and neither do you.. you are perfect as you are, that took me years to figure out, thats my shame and sadness dont let the same happen to you.
if its ok we can have some discussions regarding faith etc.. i haven't traveled the whole forum to find an area for this.. just been able to have free access to the net in the last week.. if there is a location let us know please..
hang in there girl, i have no idea either.. but what i do know is to simply be me and honest with myself. i would be confidant your birth mother wont thro u out, i mean your living with her now...
so hang there, its only up from here... ask yourself one question " whats the worst that can happen? and then what will you do?" and the answer is to get back up and keep going.. its onwards and upwards from here. you have made it this far, keep going
