Help please! How to get over someone I'm constantly thinking about?

refocus your mind on something else, family, friends, shows, или even other Любовь interests.

best Совет is this, play some video games, watch some TV, Hang out with friends, do any task that requires your attention.

keep yourself distracted and your mind will eventually find something new to preoccupy itself with.

listen to me very carefully.

Ты have to do every thing i say.

it will help you.

go to your kitchen.

get a bowl of somesort, and a damp towel.

go to the bathroom.

stare at yourself and everytime Ты thing of that person just перфоратор, удар, пунш yourself, as hard as Ты can.

and Ты wont want to think of him.

and if Ты start to bleed Ты can apply to the damp towel, and the bowl is for if Ты ever need to throw up.

youre welcome.

Do something fun! Watch awesome Фильмы (like Micheal Bay's Трансформеры или The Avengers), watch a happy Аниме (like Dragon Ball Z или Fairy Tail), или collect toys.

Hang out with other people

I'd suggest Ты should put your mind at ease and just do something to get your mind off him. For example, Ты could take up a hobby, such as Письмо a story, watching movies, hanging out with your Друзья and family, etc. Or, what Ты need to do is just think about the other things that keep both your mind and день going. These are just my suggestions and I understand if they are stupid and not helpful. :P But I wish Ты luck.
