I was exactly like that a couple of months ago. My teeth are quite tight together and I was struggling with floss. I can only say it gets better with time. Give it a couple of weeks and it will become easier. Now I cannot go to bed without flossing. Good luck!!
The only way I get myself to floss is by using floss picks. I also try to floss while doing something else so I'm distracted I'm not thinking about flossing
