We live in a world, Ladies and Gents, where there are unfortunately a lot of people with low self confidence, and I feel your pain people. I have had a number of years I spent with quite low self confidence. I always did things to make others happy over myself (which isn't much of a bad thing) and I never really had the courage to stand up to many people.
Over the last year, I have found that my confidence levels have been getting higher. In 2014, I left my sixth form year behind, which had my confidence levels sinking from being so worried about failing, and being someone who struggled badly with the subjects I had chosen. I spent a few weeks away from home at my grandma's house, where I was away from everything that could cause me stress, and my mum challenged me to a social networking challenge called '100 happy days'. This helped me a great deal, as although I didn't finish the challenge, it helped me to find something (even the smallest thing) that could make me smile through the day. Whether it was just seeing a family member I hadn't seen in a while, or eating a meal I really enjoyed. One of them I remember was just having a few hours to myself where I could just sit with a coffee and read, and not be bothered by anyone. Last year, also, I began to have the attitude of being able to not care what people think. This is a hard thing to begin thinking, and it was difficult at first.
I accomplished this by speaking my mind, no matter how silly or embarrassing it was and trying not to concentrate on how people would react to it. I tried to think to myself 'what would it matter to me what other people thought of who I was?'. There were a few times where I had to mentally tell myself off for caring. This will not be easy for anyone, and a lot of people may care a lot about what people think of them. I'm not saying you shouldn't care, but if people don't like you or don't like something that you have said honestly, then why would it matter? Unless you have offended them or said something you really shouldn't have, then it shouldn't be a huge issue.
I am working towards being able to look in the mirror now, and being able to smile and be happy with the way that I look. I want to be someone else, someone unique to the world, I want my cares to be miles away when I'm happy, I want to be friends with who I want, and like what I want.
This, as I said before, won't be as easy for everyone. If you are struggling, there is NO HARM in asking for help and there is nothing to be embarrassed about. When your confidence begins to grow, you will know.
This is just my personal story, to help to create more happy, beautiful and confident people in the world who are happy with who they are. There is always help for those who ask for it. Smile and live, everybody.
