Don't bother?

Recently friends have been asking me out, but I rejected some or perhaps all, to be fair. Just need a little understanding here. I'm retaking my O levels again and I'm not going to neither Polytechnic nor ITE, not even Private institutions. So can you please fucking understand? -.- You know whenever I tell them I need to study, I get fucked up replies. These few days had been really bad. I've met a liar whom lied to me for so so long and I felt like a bitch. I only have a piece of good news which is, I've lost 10kg after 5 months.
