The people enrolled in this training program are your research community, and they are one of your most valuable resources. Think about forming a writing group with some members of this community - people with whom you can swap ideas, who will proofread your work, and who will keep you motivated. Or join the Shut Up and Write! group run by ReDTrain! The members of your writing group don't have to be in the same discipline area as you - in fact, it's often better if they are not, because that way you get the ideal reader of your work: the educated reader, someone who can understand what you are talking about, but isn't necessarily familiar with your field. Make it your mission to follow up with someone who you think might work well in this way for you.
