I'm so confused

I so badly wanted one more baby and it to be a girl and I would get my stuff taken out and live my life with my children. When I found out this baby was a girl I was over the moon and back and then the dad left me I didn't want to be alone in this I don't want to go into the hospital alone I have 5 other kids and I'm doing a fine ass job on supporting them all alone but now it has been on my mind that maybe this is to much should I have another baby with out. Her dad around will it be to much for me I know I wouldn't have a love life when I'm single with 6 kids but I don't care about that everyone wants me to put her up for adoption it's be eatting away at me. Could I bring myself to do it how will I feel after I do it. There's so many ppl out there that wants a baby I just don't know what to do I keep crying and over thinking everything don't hate on me I love my children I'm just so confused on what to do any more
