First, read the English article below.

Even if you went through a similar experience, realize that everyone copes in different ways. You may describe how you felt during that experience or suggest ideas that might help, but understand that the other person may be going through a different struggle.  Instead, try saying something like, "I can only imagine how hard this must be for you. I know how sad I was when my own dog died." Most importantly, never claim that your own problems are more serious (even if you feel that way). You are here to support the other person. Acknowledge that the other person's problems are real. Focus on listening to his/her problems and supporting him/her as s/he deals with them, not telling him/her that they're not worth the attention.  Try not to accidentally minimize or invalidate your friend's experience. For example, if you try to comfort a friend who has lost her pet by saying, "I'm sorry you lost your dog. At least it could be worse - you could have lost a member of your family," you're actually invalidating her grief for her pet, even if you don't mean it that way. This could make her feel reluctant to share her feelings with you, or even feel ashamed of them herself.  Another example of invalidation is the well-meaning, "Don't feel that way." For example, if your friend is struggling with body image issues after an illness and tells you that he feels unattractive, it would be unhelpful to reply: "Don't think like that! You're still attractive." This tells your friend that he is "wrong" or "bad" for having his feelings. You can validate the feelings without agreeing with the idea behind them. For example: "I hear you saying that you're feeling unattractive, and I'm so sorry that hurts you. That must really suck. If it helps, I think you're still very attractive."  Similarly, don't say "at least it's not as bad as it could be." This can be interpreted both as a dismissal of the person's problems, and as a reminder of additional problems in the person's life. S/he may not be comforted by such statements, or s/he may...
