I'm so embarrased about being on medicaid...?

I've worked so hard and now that I find myself without work, pregnant and without insurance, I had to apply for medicaid. I feel so embarred holding my benefits card. I feel like a huge let down, not only to myself, but to my community that is already feeling overwhelmed by the amount of people on social services. I guess my reason is, I've worked, I love working and the uplift I get knowing I am financially independent, I feel so codependent and worthless. Everyone keeps telling me I've put into the system and it's meant to be there as a safety net, but so many people abuse the system that I feel it has a negative connotation and that provider offices look down at you. How can I get over this embarred feeling? I can't wait the last few weeks out of this pregnancy, I want to start working again! I hate sitting at home! (I'm in late pregnancy and have been trying for months to get work-had plenty of interviews-but I'm sorry-it seems like the employer sees your bump and doesn't want to hire you not only for liability, but for maternity/disability leave.)
