I worked for a friend of my fathers , I did cleaning services for her once before . So a few months back she contacted me asking to help her clean out her sisters apartment because her nephew (sisters son) passed away and I agreed . We also agreed upon $12/hour . The job description was to organize , pack , throw away , and help load the truck . Roughly 80-90% of the apartment went o good will or was sold such a furniture , pictures , plants . Whatever she planned to give to good will she said I may take instead with her approval first - another words she gave me things instead of donating them to good will . 
Things I took home : sodas , doggy food and treats for my fathers dogs , and 4 trinkets like dragons and wizards .
The soda I took for my family  , dog food for my father , and the trinkets to gift to my step father because he collects dorky things like that .
I was paid $8 extra the first day and the rest I was paid as should be . I drove myself to and from work , some days I came home and was in so much pain lifting items that my husband had to rub me down with icy hot and rub me down hard . The same day I received the trinket was the same day I shipped them to where my step father lifted costing me $40/$50 that I had earned . Knowing I was quoting my job stable job soon at the time planning to move . I knew I wouldn't be able to ship it another time . 
2-3 weeks later she texted me playing the sympathy card staying her sisters passed away son had gifted her those trinket and would like them back . I explained u didn't have them and that I had given them away , that I had shipped them to my step father . The lady took it as two different statements .
I was in a really rough spot with my husband and had just been diagnosed with depression , mood disorder , && 60% borderline . I actually shared some of my current life with her to which she used against me and exaggerated saying that I " desperately " needed the money I was working now for from her and questioning me how I could send a package like that away when I " supposedly " needed the money . She made it out to be as if I had lied to her . 
I kindly asked her tomboy to speak to me like that and that I would try to get the items back for her . To which she stated that I didn't know what she was thinking nor how she felt and I didn't need to ask her to stop basically . Yet when a person texts a LOT - an they've met the person - it's easier to read them through text . Las if you understand what I mean or comment a " Y " with whatever you write . I said I'd give em to her when my step father helps me move out of state and into their home but I ended up changing my mind last minute now owing them $500 for missed work days and time loss etc .
Then j found out that after it was agreed if get her items back - she'd been slandering my name to my real father saying I " took the items knowing very well their money's worth and lied about giving them away then lied about gofting and shipping it to my step father " . I'm only 19 . The last time I ever stole something worth anything was when I was a 4th grader . I don't even let friend pay McDonald's for me .
She said other things but it got me most that after the agreement she talked badly about me to my father . So I called my step father and explained the new knowledge of discovered && told him that I gave him those items therefore they are now HIS . And he can keep them or give me back . He said he'd keep them . So I called her with a blocked number an explained to her that she would not be getting those back .
Today I received a text stating that again I " took them " and if I didn't give me back that she would take me to small claims court . And make me pay for any trinket damages . Again over items I never kept , items I shipped the same hour I got off of her work hours , items I do not have in my possession , items that are 830 miles away items she had given away and if I hadn't taken them then they would've been bought by someone in a goodwill store .
Now my father is upset at her for threatening me . An Indian giver using sympathy card and behind my back slandering my name . 
What should I do ? I spent $40 that I earned to give them as a gift and is need another $40 to even get them for her && she slandered my name and is threatening me ? I don't want to just give her the items . She cause me a panic attack today and has caused my fathers to be upset with me . I consider her a bully .
Am I in the wrong or her ?
