Hate on me

So, a few days ago somebody asked me why i am so quiet and dont seem comfortable surrounded by people. I answered by said thats because i just dont know what am i going to say to people whom i  rarely  meet. Later he said i can talk about anything like my college life, political situation, or just newest celebrity gossip. He also said that because i dont talk too much almost everytime, he scared to start a conversation with me, he said maybe its just his feeling but then i said no, most everyone feel the same about me. I might type it with a :) symbol but deep down i crumbled. He said no offense. Dude, i already offended. I know you tell me the truth and its an ugly truth. I dont blame him at all, its me who feel uncomfortable when im with people i rarely meet and for me, it takes time to get closer with people. Family or friend. Thats why i just sit there and shut my mouth. I thought it was okay and we dont bother each other but he doesnt feel the same. Thank you for your advice but that night, i cried :(

Then tonight when my friend and i (a girl and a boy, 3 with me counting) spend an evening together and played truth and truth game. My friend asked us who's the person you unlike the most. He said he doesnt like me. I thought he was joking but then things get serious when he said i hurt him for a long time by my attitude in whatsapp messenger! I sadly start to remember all the things i said that might hurt him and end up with.. I dont know what my fault is. I asked him what it is? Tell me when i hurt you, he said i wont tell you but from now on im gonna treat you like the way you should had to. Ooh, so this is why he always rude to me.
This hurt me even more when someone told you that he hate you but wont tell you what the reason is.

Im so tired to feel hurt. I have been spending so many years built a wall inside me, telling me im okay, im not that persona non grata, and i have changed so much.
But this entire week ruin my wall, and my faith too. Do i have to be bitter again? :'(
