Do you think my sister has a disorder
My sister is 26 years old. She is 4 years older than me and I have taken care of her since I was 16. When we were both teenagers she got real messed up and involved with the wrong crowds. She ran away when she was 17 and broke my mother's heart. Anyway she ended up coming back and graduated high school and moved out when she was 18. She had 2 kids within the next two years. I have raised those boys since they were babies. Taking care of them, paying for things for them, they would never have had a Christmas or a birthday party had it not been for me. Anyway the reason I ask if she has a disorder is because my sister lies A lot! She will lie about the color of the sky and do her best to make up big elaborate stories as to why you should believe her, and then of course goes on the defense if you tell her she's lying.
We have grown up now and her lying is still an issue. Just a few weekends ago we were suppose to go out on a Friday night, and I asked her numerous times if she really wanted to go out, and that we didn't have to if she didn't want to, etc. Anyway she said yes, for sure she wanted to go out. So I went home to get ready and take a nap and waited for her to get off and she texted me and said that her piece of crap babies daddy wouldn't watch her kids so we could go out, so I said OK fine whatever, (I had an inclining that she was lying at the time anyway because she told me not to answer if he called) so anyway she said we would hang out the next night (saturday) so the next day I texted her several time's throughout the day and she did not respond. So on Sunday I called her because my whole family was at my mom's house and I wanted to see if she could come over. She did not answer... so I got worried and called her ex-husband. I told her that I was worried because I had not talked to her in 2 days and didn't know what was going on. His reply was "well didn't you and her just hang out friday night?" I said "no she told me you wouldn't watch the kids so we couldn't go out." Anyway the story goes on, that she lied to me because he ex did watch the kids and she did go out, she lied to her ex because she told him that she was going out with me, and she lied to her boyfriend because she also told him that she was going out with me.
I know this is stupid and petty, but WTH?? I mean why wouldn't she have just told me "hey I dont feel like going out tonight" or " i have made plans to go out with someone else", my sister use to have a bad addiction to drugs that I'm not sure she ever got over but I just don't under stand why someone would make up such a big huge stupid story just because she didn't want to go out. And this isn't the first time that she has done this. And her poor kids have to be put through it all the time
So I have brought it to my families attention and I honestly and truly do believe that she has a psychological issue. She lies about everything and she believe's her own lies and thinks they are true. I don't think she even know's what the truth is anymore. So I just wanted some other people's opinions as to if you think she does or not. I seriously think she needs some kind of intervention. I don't know but I am really the only one from my family that still talks to her, and I'm starting to stray away from her a lot more. I just don't know what I should do about this.
