Trouble Hand Expressing Colostrum

I'm 37 weeks today and have a lot of anxiety about breast feeding- I'm actually looking forward to the birth (crazy! I know!) but I'm dreading breast feeding because I'm afraid I won't be able to in saying that it's really important to me that I get to try. I don't know if it's normal to have nothing at this point and I don't have any appointments with my midwife/obs until next week. 
My midwives/obs recommended I try hand express some colostrum for storage starting at 35- 36 weeks, and I have been trying literally every day in and out of the shower but nothing is happening. I've tried massaging my boobs for 5-10 minutes before and it doesn't make a difference. It's making me worry that I might just never have anything(which I know probably just sounds dramatic) and I'm embarrassed to tell my partner that I'm not making anything for our baby yet.
I just wanted to hear everyone else's experiences regarding this sort of thing and when they were able to start seeing results?
