The research masters battle

A

I am a mature student doing an ma by reserach after 17 years in industry. I love learning and enjoy my area and could stand up and talk about it confidently. However, I seem to struggle with writing in that it takes forever and my supervisor never gives any positive feedback or encouragement . I am 1 year into it with nothing much on paper and I wonder if this is normal? I am exhausted most days and find I am starting to question my own ability now! Any advice from someone at the other end? Thanks
