Hi! Maybe you are trying to change too many things at once. If you are used to eating and doing things a certain way for years and years you can't change things all at once. Try setting small closed ended goals. These goals have a means to an end. Like, how about drinking 3 glasses a day for lets say 5 days. This is very easy to accomplish. I know it doesn't seem like much but you will be surprised how empowering it will be once you accomplish it.
Try and avoid open ended goals. These goals are complex and there is basically no means to an end. For instance, lets say that you want to "Live a healthy Lifestyle". Take a look at this and think of all the things you will need to do in order to accomplish it. Stuff like, eating healthier, exercising, resting and so on. If you simply focus in on "eating healthier" think about how much you will need to do to accomplish it. You will have to eat fruits and veges, drink 8 glasses of water a day, exercise at least 3 days a week, eat certain foods in moderation. Now that you have this example think about how long you have been eating and doing things for years and years...... That's a heck of a long time to change things all at once.
Most of all, be good to yourself. Cut yourself some slack. You can't change it all in one day. Live in the moment. This isn't a race.
