Dear, I have been a supervisor for many projects, so I can understand the duties of supervisor. I must advice you to keep writing in journals and also send the same in Nature qualify journals as well. You must also at the same time keep your self motivated and complete your research projects. In case you need any help you can always ask for online help or use google search. In fact when i did my master my supervisor also behaved in the same way, however I kept my self motivated towards completing the dissertation work and out of 18 students who was enrolled I was the only one who completed the masters program on time.

Dear, For any technical writing it is necessary that the sequence of ordering must be specified as all the correspondence needs to be done with first author only. Moreover in general their is some thing called "Academic Performance Index (API)" in case your are a first author then you get 100% credit for the same for your writing, in case you are second author then you get 20% less credit and subsequent authors get their share.

Hope that this helps. In case you need any more suggesting do let me know.
