I think you need to set boundaries with her. Let her know that you are happy to talk with her once a week/twice a week etc, but let her know that if she tries any of this prank stuff again, you will stop all contact with her.

Just think, if she wasn’t your sister how would you deal with this

Look, I think I’ve said this – this really isn’t normal. I do think you need to investigate further, but also be quite blunt: if she doesn’t stop it, you’ll take legal action to end the harassment. Because that’s what it is.

I think she is feeling insecure /lonely and is reaching out to you for comfort. Was your relationship with your sister this close before? Did something happen to her recently for her to reach out? maybe
set some boundaries like keeping in touch via sms or Facebook on certain days and other days can ring like
Once per week.

Possibly sit down with her and ask her if everything is ok, and you have noticed she is becoming very clingy. She is your sister, you can tell her anything. Just let her know you are in need if space and you will contact her when you are ready to.

It sounds like she is calling out for some help. Maybe she is going through a tough time and needs someone to talk to. Maybe you could ask her how she is going and if everything is alright. Let her know that you’re there for her but you may not be able to talk to her everyday.

I feel that your sister is playing games with you. Wanting to disrupt your life as much as she can and she gets a kick out of it. Make sure she is well and not suffering from a mental health problem. Does she work or have plenty to do in a day. Ask her what she needs from you. Listen to her and then decide what needs to happen so you can deal with her bad behaviour. Especially if this is a sudden change in her behaviour towards you. I had a friend who was very demanding and was a bit of a stalker and constantly messaging. After a while I confronter her and asked her to seek help she was tested for Bipolar.

I remember once I had a friend who bombarded me with many messages a day and also expected me to take her calls all the time. It totally overwhelmed me and after talking about it with a psychologist I made clear to her that I would tend to her messages on set times and happy to call once a week. This was a friend, not a sister

I think it sounds like your sister is trying to connect with you the only way she knows. Maybe she needs some encouragement to get out of the house more and make new friends. I think it’s best if you have a talk with her and make your boundaries very clear.

This would give me so much stress and anxiety I think you should just go no contact with her you dont need this in your life and all she seems to be doing is causing you stress and it needs to stop

I’d change my number and not give it to her… and block her if she gets hold of it. But you also should talk to her, because needing daily contact is not normal.

This sounds like an awkward situation for you. Have you sat your sister down and explained how much it is bothering you and why she feels the need to do this? To me it sounds like she is not getting enough attention and is acting out to seek your attention. Does she have friends and a social group or is she someone who spends a lot of time on her own? perhaps she needs to be introduced to some groups to keep her busy and meet new people to get the connections she needs and the attention. It doesn’t sound healthy to me that she is doing this. I would be frustrated and over it too.

It sounds like you sister is reaching out for connection or contact. It does sound like she is going about it unproductively but sounds like you need to talk with her and see what is going on. Particularly if you have been close in the past and this is unusal behaviour

Sounds to me she is eager to have contact with you. What type of person is she and more important what is your impression of how she is doing ?
Attention-seeking tendencies are often linked to low self-esteem and loneliness. For many, attention-seeking behaviors are a way to find connections with others that may not be present in their daily life. Most humans need attention from others to support their overall well-being.

Sit down and talk to her about it face to face. She must be trying to get your attention for a reason. Is she feeling lonely or left out. Maybe set a certain time of day for a weekly catchup or chat.

Have you tried sitting her down and discussing this topic. Might be worth a try

Perhaps she has some sort of Mental health issue.
If its not something you feel comfortable addressing with her and you really dont want to deal with her then perhaps necxt time you decide to change your mobile number then dont give her your new number and cut ties. There is no rule to say we have to stay in touch with family members that bring negative energy to our lives

Have you tried to set reasonable boundaries with her? Tell her directly that you aren’t available on a daily basis, or multiple times a week. Signing you up for events sounds very frustrating. The best you can do is communicate your expectations and if they aren’t met I’d put her on a soft block for a few days.
