Try Not To Be So Shy

I am shy and i hate it. i meet people like friends of friends and i say about 5 sentances through out the whole day seriously. im even shy around family like nan and grandad uncles, aunties and cousins, also friends parents too. Like if they ask me a question i guaruntee it will be answered with a “dont mind” “no” or some other sort of at the most 5 worded sentence! The only people i tend not to be shy around is my mum and stepdad also all of my friends at school i don’t know whether this is because i spend so much time with them but i really want to sort this problem out it is soo annoying and embarrassing at times..Does any one hav any ideas of helping my confidence grow!? xx
