Life sucks

I am 14 (turning 15 soon) and i came out to my parents as bi when i was 13 and it did not end well, i got grounded for 4 months and they didn't let me talk to anyone they found "suspicious". My mom is ill and old, and she doesn't deserve having a failure as a child. I probably will be my true self and this thought is eating me alive. Needed to take this off my chest, have a good day.
