It sounds like there may be some underlying issues and miscommunication at play here. As a 15-year-old, you have the right to take care of your own needs, including preparing food for yourself. It's essential to have open and honest communication with your brother about the situation and try to understand his perspective as well.
Here are some steps you can take to address the situation:
Choose the right time to talk: Find a calm and appropriate moment to discuss the issue with your brother. Avoid confronting him when he's already upset or in a bad mood.
Express your feelings: Let your brother know how his behavior is affecting you and how it makes you feel when he gets angry at you for making food.
Listen to his perspective: Give your brother an opportunity to explain his side of the story. Try to understand why he reacts this way and what might be bothering him.
Set boundaries: Clearly communicate your boundaries and needs. Let him know that you have the right to take care of yourself and prepare food when you need it.
Seek parental guidance: If you find it challenging to resolve the issue with your brother, consider talking to your parents or guardians about the situation. They may be able to mediate the conversation and offer support.
Find compromises: If possible, try to find compromises that work for both of you. Maybe you can agree on specific times for cooking, or you can work together to create a schedule that respects each other's needs.
Respect each other's space: Encourage your brother to find a more appropriate place to sleep if possible, rather than on the couch, which may lead to misunderstandings and conflicts.
Seek professional help: If the situation persists and becomes difficult to handle, involve a family therapist or counselor who can assist in resolving conflicts and improving communication within the family.
Remember, as a teenager, you deserve to have your basic needs met and to be treated with respect and consideration. It's essential to communicate effectively and find ways to coexist peacefully with family members.
