Anti social , Low-self esteem, Highly unmotivation , DUN CARE ..

I feel that I am always a negative person.
Some reflection on myself for recent events.

Found out that I am more and more anti social , I dont wish to go any where, just trap myself in my little world, my only friend is my "notes" and programming assignment.

I dont barely care anyone feeling and look down upon myself all the time. Dont really aware of what is happening to the surrounding.

Just have the feeling of DUN CARE after 4 years studying in Singapore.
Everyone rush me and ask me to look for my job early, I just dun feel like doing it , forcing myself to do it . But the fact is I need to do IT.

Just keep on struggling and doubting myself.
Some good things to reflect on, recently I found out that if I remain calm and relax, I can understand all the "notes" in a few hours rather than I spend whole day looking at the notes but nothing go inside my brain for process.

What should I do?
