I'm going insane trying to keep track of my finances. I purchased a binder (it's like an accordion, pretty neat actually) from Office Depot, and thought it would help me...it's just not working. I also have a roommate and have no idea how to keep track of what she should pay. She also recently wrote me a $250 check and I lost that...so she said she would make up for it by purchasing groceries (with her free $300/month EBT card), but I'm not sure if that's completely fair, considering I can't figure if that would be over the $250/month I could have gotten. Suggestions?
