Unplanned pregnancy

I just had my daughter in april 2017 and wasnt wanting another baby until she was at least 3 or 4. Her dad and i broke up in october but are still on great terms and i just found out im pregnant again with our second. Ive never faced something so difficult. My daughters fathers dad committed suicide in september and he already has so much on his plate, we used to live together but since we split we had to move back in with our families. Im so scared its not even funny and im not even sure if abortions an option for me. I dont know what to do 😭 any positive advice and support is so needed right now. Im lost.
