I've been annoyed with my best friend lately! help?

you defianlty should not avoid her, that'll just make her more depressed cuz itll make it seem like u dont wanna be her friend anymore. explain to her that ur busy and that u do care about her and wish u could spend time with her but for the time being u have too much on ur plate. TRY to find one day out of the week, if u can, to just spend it with her, thatll make her feel loved which might cheer her up. other ways to cheer her up? well when my friends are down i just remind them of fun times we've had and i thank them for being such a good friend. it cheers themup knowin that they make me happy. hope i helped (:
