My sister is very depressed. She blames me of creating troubles and she has nothing to do with my problems

Dear friend, I am sorry to hear that your sister is struggling with depression and that she is blaming you for the problems in her life. It can be incredibly difficult to witness someone you care about suffering, especially when they are unable to see your good intentions. From a Buddhist perspective, it is important to remember that everyone is on their own individual path and that we cannot control others' reactions or emotions. It may be helpful to approach this situation with compassion and understanding, recognizing that your sister's depression may be clouding her perception of reality. From a psychological perspective, it is important to set healthy boundaries in your relationship with your sister. It is not fair for her to blame you for her problems, and it may be helpful to have an open and honest conversation with her about how her behavior is affecting you. It is also important to prioritize your own well-being and seek support from friends, family, or a therapist if needed. In terms of coaching advice, it may be helpful to approach your sister with empathy and understanding, while also setting clear boundaries and communicating your own needs. You can encourage her to seek professional help for her depression, while also taking steps to prioritize your own mental health and well-being. Remember that you cannot control your sister's actions or emotions, but you can control how you respond to them.
