Am I on the verge of having a mental breakdown?

I don't think you are on the verge of a nervous breakdown but are in the need of release of pent up anger and unresolved issues find some one you can talk to that will not opinionated but a listening ear, the more you talk about it the better you feel, seek professional help it does not hurt to talk to a psychiatrist. It does not make you crazy, you are talking to someone that understand the human mind
