<human>: I dont exactly even know what Im asking but ill tell you whats going on. This year I've started an HND course in IT that Ive found out I have no interest in, I sit in class all day staring at the computer screen learning about networks and whatever else and looking around at my class just thinking "Wtf am we doing here, what use if this to anyone?"
           I just sit with what feels likle an enduring burning mass in my navel looking out the window then back at the class sitting there typing and the teacher sitting there saying nothing. Today I was sitting in the same routine as Ive just explained thinking -and I was fully serious- of just standing up and breaking a PC and just saying to the class "what is wrong with all of you? This is not human" or something, but I thought "nah that wouldnt awaken people or inspire awe in the their hearts, itd just make me look a bit insane and possibly give them a little entertainment.
                   I literally carry this fire in my veins calmly throughout every day in state I would describe as "calm like a bomb" , even while I sleep, Ive tried to just knuckly down and do the assignments but I cant focus because I think Ive crafted my mind over the years in such a way that Ill probably end up homeless before I make a living doing something thats actually of value to humanity in atleast a little way and I think thats what will happen if I dont find something to pursue soon.
            Ive been looking at jobcentre websites etc and just close them in anger at how mundane and fruitless all the jobs clearly are. Didnt realise how much I rambled there until now, anyway Ive sort of been like this since about 14 and at that time it was probably mostly teenage anst and not what now but im nearly 21 now, so im very much in a real situation here. What should I do?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I really dont know, I tried to fashion this into something respectable that explains my situation so someone can help me but Ive failed and am open to any advice someone might be able to give.
