17 and scared

i made a few posts about being pregnant at 15 and losing the pregnancy and then pregnant again. but this time around i feel constantly worried. i feel like any way i go i’ll be fucked. if i miscarry, ill go through depression again. if i decide to not keep the baby, i am very afraid i’ll regret it. if i decide to have the baby and keep it, i’m scared i’m going to not be happy with what i did with my life. i hate the uncertainty and i am constantly thinking about all of the above. my first scan isn’t until march and i’m going mad. abortion and putting up for adoption is not an option, i have an amazing family that will support me no matter what and until i will be able to get my shit together but does anyone have any advice on how i can take a chill pill. 😩(also get lectured plenty enough, im well aware the situation i’m in is completely my fault)
