Hi Alpha, sorry you are struggling. Are you a minor living with your sister or an adult trying to figure out how to navigate a relationship with her?

Honestly, the things you describe do not sound like abusive acts. People close to us hurt our feelings sometimes and get annoyed with us at times but that is not the same as abuse. Not buying someone a gift (your uncle I think you said) is not abusive...neither is refusing to loan an item to someone (your sister). Looking at someone with an angry facial expression is not abusive. We all feel angry sometimes...and probably look that way too at the time. I point out the distinction to prevent you from heading down the wrong track while you are working through this but of course behaviors don't have to be abusive in order to cause problems and confusion for us.

Have you ever talked to a psychologist? Someone with experience in family therapy? If you are an adult, I suggest creating distance from your sister. If you don't like her, don't enjoy being around her, then I'm a bit confused about why you are spending so much time with her or thinking about her. Did I miss a piece? Do you live together?

If she's lying about having a friend or where she stays, why do you care? Let her lie. That's for her to deal with in her life. If honesty is important to you, that's a wonderful trait so focus on your own honesty.

We cannot change other people; we can only change how we respond to them. Trust me, my siblings have hurt my feelings more times than I could count but now I just keep a distance and don't expect much from them. Does that make sense?

I wish you well. Try to bring your thoughts and focus back to you. What do you need for you?
