Am I pretty? Why do I feel fat and ugly? Why haven't I got a boyfriend? Have I got enough friends? I'm not going to pass my G.C.S.E's and then I won't get the grades I need. My self-esteem is so low, HELP!

Low self-esteem often begins in childhood. Friends, siblings, parents and the media give us positive and negative messages and for some reason we focus on the negative. If we don't tackle this early it can lead to anxiety and depression in later life.

Improving our self-esteem is easier said than done when you feel unworthy, not good enough, pretty enough or smart enough but there are lots of ways to make yourself feel better...

Don't compare yourself to other people. There will always be other people who are prettier, smarter or more popular. Don't let this get you down and punish yourself. Find something positive about yourself i.e. I am a good friend, I like my hair today, I look good in this outfit and say it out loud or write it down so you don't forget.

School can be hard and stressful so try and find clubs and groups away from school and make new friends. Being friends with others based on your interests can be easier than just because you are in the same class.

Get active or sporty. Getting fit improves your body image and the way you feel about yourself. Going for a walk, taking a bike ride will release endorphins, feel-good chemicals that make you feel amazing. Try changing your diet too; eat more fruit and vegetables and instead of always having fizzy drinks, have a bottle of water or some fruit juice.

Don't hide away if you at upset. If you isolate yourself, your feelings get worse and harder to talk about. There are lots of people who understand what you are going through and you are never alone. If you can't talk to your parents or friends there are lots of organisations such as Childline or Young Minds who have people that will listen and more importantly not judge.

Remember how brave you are for wanting to get some help and don't ever think that you are the only one struggling.
