Hi
Thanks for letting me know how things are at home with your cousin.
You explain really well how your cousin is annoying you by trying to get your attention, winding you up, wearing your clothes and playing loud music when you are trying to revise. It sounds like you have tried talking to her and it makes no difference and you feel that your mum isn’t listening or supporting you.
Exams are a very stressful time for a lot of young people and sometimes when we are stressed, even small things that we would normally be able to cope with can really wind us up and get on our nerves. You might like to have a look at the Beat exam stress page in the Explore section - there are resources about exam stress and ways to cope with it. You could also have a look at The Site website which also gives some hints and tips about studying, revision and coping with exams.
You say that your cousin wears your clothes and you feel that you have to buy new underwear because she also wears that. What would it be like to take more responsibility for your clothes by washing, ironing and putting them away in your room? It may be that you have a lock on your cupboard or your room door which would mean that you can keep your things safe.
It seems like your cousin is trying to attract your attention by doing things that she knows irritate you. How would it be to explain to your cousin how you feel about this? You could also try telling her that you will spend some time with her at a specific time and stick to it and do something with her that you both enjoy doing. This would mean she gets your attention but at a time when it is convenient for you.
Don't forget you can talk to a ChildLine Counsellor whenever you would like to. You can phone for free on 0800 1111, or go online and use 1-2-1 chat. You don’t have to tell them your name or anything else about yourself, and you might find that talking to them will make you feel better.
Take Care
Sam
