sad and heartbroken

im angry at the world and sad i was hoping for this pregnancy to go threw all the way. i went in my appointment today they found no heartbeat the baby is measuring at 6 weeks and 4 days but my gestational sac is measuring at 7 weeks and 1 day. they gave me three options of what i can do and i was thinking of just letting my body miscarry on its own but a part of me still has hope amd i feel crazy for thinking some how my baby will have a heartbeat and keep growing. i just don't know what to do or feel.
