How can I stop waking up sad? I just want to forget

Before you go to bed at night, write down 3 things that you are thankful for or that make you happy. Try and create 3 new things every night. It really makes you think about what you love and care about. Even just a little positivity can improve your day tremdously

Everytime you go to sleep, sleep with the vision for the beautiful next day nd have gratitude in heart for the day you had. When you get up say thanks to the universe for the amazing day...!

Try to go to sleep with a positive goal for the next day. In the morning, try to achieve it. For example, a goal could be to work out in the morning or greet at least five people. It could even be to complete something you haven't gotten a chance to complete. This way you'll have the opportunity to wake up with a positive and determined mindset and be focused on achieving a goal instead of thinking about negative thoughts. It's a good way to distract yourself from your thoughts and grow as a person.

do something that will take your mind off of whats making you sad .

Think of all the positive things in your life and make a few changes to your lifestyle, see how its going to have a good impact on you!

before bed you can take a relaxing bath and when you wake up make the first thing you look at something positive

It could all depend on what you're trying to forget. You can try to do things that make you happy before bed and/or right when you get up. If this problem doesn't resolve itself you might want to consider talking to a counselor

It depends on exactly what you want to forget, sometimes forgetting is not the answer, maybe you need to solve the problem instead of running away from it by sleeping or forgetting.

Distract your mind, read a book, watch a movie, join a dance class, walk in the park, go for a run do anything to help you forget whatever has you hurting so much.

Think about good things. :) Waking up to another morning is enough reason to be happy. Always choose to be happy. :)
