I don't think it's daily angst, more a constant stream of unfiltered awfulness directed at yourself. Seek help dude, for serious. This is not a normal way to go about your existence.
Is the consequences of actually speaking to the school counselor and maybe getting some help to pull yourself out of the quagmire actually going to be worse than going through this every single day?
Gamedragon--one big thing about one's self-hate or such, is the thoughts they apply onto themselves. Self-hate lies in the thoughts directed at you, which includes the conclusions you make about yourself. At times, this can include what you see about yourself that goes in a pseudo-cyclic observation and conclusion cycle (eg I'm not that active, thus I dislike my lack of activity, and then certain demeaning thoughts along that line hit me, then that maintains the lack of activity because of the feelings of futility and otherwise coming from those ideas), although this is just one way about it.
Please contact those to help you. The ideas that keep you at an unhealthy feeling are not permanent, nor should any conclusions be drawn from them. Also please don't spoiler your posts--every little bit in your actions is important here. If it's venting, that's ok--follow it up on your part there with ways to face that. If it's something you actually believe in yourself (ie I'M A PIECE OF SHIT!), stop that thinking, and move from it in a better light. None of us can help you other than giving details--details better given in physical contact with other people there. Intrusive thoughts aren't your friends.
Gd's school counsellor is unsuitable IIRC, and he's in an awkward position with his parents.
NEXT BIG THING: If you feel the current mental health professional is unsuitable to your comfortability--you can INQUIRE for a referral to someone else. A person within this profession, instead of the usual assumed reaction of a {bad reaction}, will go along with this, because it's something noted in the ethical guidelines
applicable to the profession as a whole, within bounds of professionability; counselors can understand that at times, the people that come to them may be uncomfortable due to several issues, even if these issues may not actually be what's happening, so they bring other people to help you. Otherwise, trying again with your counselor won't mostly make anything worse. There's a big difference in professionality here in that they aren't out to 'get you' no matter how awkward or {other uncomfy feeling} you think about or apply to yourself.
