"What doesn't kill you makes you stronger"
I am mad jealous of children whose parents made them do outdoor activies. Heck I wish I wasn't even born (can't suffer again neck fracture, unless a gun does the job I live on). I am mad jealous at other rich spoiled kids. Heck I am mad at useless bullshit jobs. Heck I am mad at meaningless cosmological nihilism that we all try to avoid. Heck I am mad for being a nobody without any social life, hobbies and even failing at exams.
I do not know if anger helps you fight your circhmstanced or is just detrimental?
I think that depends on how you react to that anger. Generally there is a core need that is underlying that anger. Once that core need is identified, it may be that the anger turns into a different emotion, and will also start to provide avenues for dealing with that need.
Eg. if the anger is related to failing at exams, on reflection it may be that you determine that this is affecting you because it may affect your future career prospects, ie your need is to secure your financial future. Or perhaps it is due to another need. The underlying emotion would then be perhaps fear or anxiousness (or it may be something else). Anger is the unrealized version of this emotion. Once you have identified the underlying needs and emotions, that will start you on the path to fulfilling those needs.
