I have to start by saying laziness and procrastination are very common but it is easier to quell than most people think. This is probably because doing nothing is easy and soon, one can find comfort in ennui. It's a thing of the mind and I'd advise you to start doing more mental and emotional exercises.
You should start by doing the little things. Maybe your room or set small goals for yourself which could even be in the form of writing. A thousand words a day? Sure. That'll give you confidence to do more or develop some sort of consistency.
And also, nobody can really help you change or get better until you are really serious about being more industrious. This is not an attack or anything; I'm just trying to be honest here and let you know that you really have to be serious about DOING stuff to not be lazy anymore rather than SAYING you don't want to be lazy. Life is much shorter than we think, so it's best to make every minute count.
Hope this helps.
