It’s important to keep in mind that bad time doesn’t last forever and our existence is made of negative, neutral and positive occurences.
I know it doesn’t sound appealing to a person who has been suffering but right now PLEASE focus solely on yourself. If you are in the harmful environment PLEASE plan the great escape. Eat healthy, sleep enough and rediscover your hobbies, wishes and desires. You are the the most wonderful & unique person who deserves the best in life. Only if you remove yourself from a negative situation that will be possible and healing process will take place.
