Career worries

I'll be turning 34 this summer and I'm still not established in my chosen field, a highly competitive arts field. I've done some freelance work, but never for longer periods. I've been stressing about this for a while, but now that I'm pregnant I'm even more stressed out about it. I'm due in December and I've been to several interviews in the past couple of months, trying to land something before I'm showing, but nothing has come of it so far. I was really close to getting a dream internship at a major studio, I was in the top 10, but wasn't one of the 8 lucky ones.

I'm working part time at a job that most people have for a short time while studying and I feel ashamed to tell anyone besides my family that I'm pregnant because I don't even have a "real" job yet and I feel like a major failure. I worry that if I don't get a job now before the baby arrives, I'll be so old that employers will be concerned about my lack of experience. And I worry that I'll get stuck, because most of my employment possibilities are abroad and even if my partner says he is totally open to moving, maybe parental leave, his job and other practicalities will make it difficult. My nightmare vision is that I'll turn out like my mom who never really had a job after having kids and who never had the career she wanted.

Anyone in a similar situation or with any thoughts or advice?
