I'm boring! What can I do to make me more interesting / a better person / happier? ?

First of all i understand how u really feel.Sometimes people think they are happy but deep down inside they are really lonely.I'm happy u dropped all u have considered bad habits.Take things slowly,don't be too desperate either.Sometimes,when people desperately try to make themselves happy,they normally end up settling for less than what they deserve. I'd say in your sparetime try to do some creative things.Pray and ask God to make u a happier person(father alone will understand why).Everything will be just fine just take life one step at a time!And good luck in pursuing further education!And ms right will find u by the help of God so dont give up!
