I don't know if this is valid but

long story short, is it valid to feel the need to distance yourself to a friend na idk "draining"? I have this friend na kapag may problema s'ya or dinadamdam s'ya she tends to distance herself and that is understandable tbh. but what I don't get is alam mo 'yung feeling na para kang nadadamay? most of the time when she's in that state, I feel like a punching bag, she nags, she throws her tantrums, she outburst on me, she gets mad at me easily kahit para sa akin wala naman akong ginagawa. Kunwari sa group project, she did her part and I said "wait waitt, edit ko haa. ganito kasi format na sabi ni sir--" and then she's suddenly so mad about it saying something like "Oo nanga mali na nga! edi sorry kung hindi ko alam. sorry kung mali yung ginawa ko! pwede naman sabihin nang maayos" etc etc. Like I totally get it if she's suffering from something and she's not comfortable enough to share it with me but it feels tiring to have no idea what she's going through tapos magiging punching bag pa ako, waiting her to be okay.
