Worried about not bonding

I've had multiple miscarriages and also two healthy boys currently pregnant 24 weeks with another boy. My life is really stressful. I'm talking both mentally physically and spirituality. I'm not having much support from family or friends due to their own lives. My family has been dealing with one crisis or another for ever it seems like. My health is really poor and this pregnancy has been very hard for me. I feel as though I'm not bonding with this baby like I have with my previous pregnancies. I am concerned with the amount of stress I'm under I won't bond with him when he arrives. I literally have done nothing to prepare for his arrival and have no energy, time, or money to prepare anything for his arrival. I can't even get to agree with my husband on names. I'm feeling so lost this time. I'm in and out of doctors offices and hospitals because of my bad health, juggling my kids as I'm a SAHM, juggling my job, my family, my extended family's crisis's. I'm so burned out and feel so unattached to my baby. I feel so terrible to admit it. I don't even know how normal or abnormal this is. Has anyone else felt like that? How did you cope? Any pointers?
