i dont think i can do this

im not married, my boyfriend is deploying for a year, i still have school left, im only 22 and i don’t know if i can do this. my mom is so upset and told me i was irresponsible and i just don’t know what to do. my parents support me and we are well off its just scary the thought of growing up and my life completely changing. i was on birth control but this was completely unplanned
