career development

I went to a workshop today on writing. I was hoping it would have helpful tips so that I can avoid the black hole of writing that I see many dissertation students fall into. The presenter was an MD who had never written a thesis but still had some good suggestions for dealing with writers block and ideas to make writing a habit. I also heard back from two possible labs for maybe post-doc spots. I will be meeting with them both at my annual conference :) I still have a few people to email, but every time I email someone I get a sick feeling in my stomach. What if they say no? what if they agree to meet me only to say nice to meet you, I have no funding. (I got an email like that and am trying to decide how to reply, because they would meet with me if I found funding) But how do I find funding when I'm not sure when I'll be done (probably not until next December) and am trying to collect data, analyze it, write up papers and write my dissertation? I think I'm going to be stressed out until the meeting happens and then I will be stressed out until I know I might have a place to go.
