Basically this past week i have Had � � body run dwn and friends and family have advised me to tke complete bed rest so i hve been doing Tht. But jst � week before i asked MY friend shall we go job hunting for u as she was asking for weeks for me To help so i said ok. But due To me failing sick this while week i couldnt go so i rang her up n apologised To her and asked if we can go another time. She was so rude To me and said i always mke plans and Never fullfill dem and hnged up on me. I felt so hurt by her actions i admit i hve Had � Few occasions were due To wrk i couldnt go out with her or Anyone. But theres also another thing WEN we do go out i always buy her food as she has � struggle with money. She Never says thankYou or nothing now her friend accepts me To buy her everything as well when i dont really no her. Other than that shes � good friend i dnt mind helping her but her actions have started putting me off her.
