[cranky] so broke, so pissed

I can literally feel a stabbing pain in my chest. My two $25 birthday giftcards are gone. Who has been in the house since I recieved them? Realtors, prospective house buyers, my good friend "J," and my old high school friend and new friend-without-benefits "Jack." About a month or two ago I had a disappearing cash meltdown -- was Jack going through bags, to find my purse, to find my wallet, to take cash?! Twice? No way. Has Jack managed to walk off with giftcards that had been tucked away? Is that what he was doing instead of cleaning the kitchen after he made midnight dinner a few nights ago?

Previously the thief was my younger sister -- stealing keys, making copies, and sneaking in while we were at work to steal cash and sell-able anxiety meds (usually klonopin). I feel like the biggest fool letting someone into my home and having money disappear. There is $5.05 in my purse right now, all in coins. That's all I have. Along with no job and a student loan payment due in 7 days.

My sister has Borderline Personality Disorder (BPD). She was diagnosed when she was 17. There is a list of 9 "symptoms"/behaviors and you have to have 5 to get your gold star... she has all 9. Very briefly... she was drugged and raped at age 14 setting her off into a downward spiral of shit; by 15 she had admitted to us that she was drinking heavily since nearly age 13 and she also thought she had a miscarriage without actually having had sex; by 16 she had her first tattoo out of a pay-by-the-hour motel and was dating a 31 year old man with 4 kids from 4 different moms; at 17 I took away her PTI freebie and she had to be processed at the state prison after she stole my identity and all of my money while I was out of the country, she was a member of the Crips, got checked back into the psych ward, and skipped town for several months with my mom (to this day, I'm not sure where they went), after they came back in town she was checked into a residential outdoor rehab center and was their longest ever patient-- turning 18 at the facility and choosing to stay. By age 19 she accused me of molesting her repeatedly as children, and now at 20 I'm forbidden from being in the same building as her, per my mother and grandmother's orders. J has seen her out at bars several times, and she's going to be 21 in a few months. She's claimed to be an alcoholic since she was 15, and now she's regularly drinking and driving and the only person that could possibly stop her is my mother who is afraid of running her off. She is capable of constructing entirely alternate realities, alternate stories, events, persons and then believing them whole-heartedly.

Despite my father and therapist telling me otherwise, I feel like the ultimate dumb shit for allowing money to walk out of my house. I know better. I know the signs, I know what to look for. I let my guard down, and I feel like an idiot. I think there's some chocolate box cake mix in the cabinet I can make, so I can save that $5.05 for something... no clue what...
