I am sorry to hear you feel like this. School can be a lonely place if you have few friends and when not occupied the days can seem really long and the weeks drag until the weekend. It is a tricky question to answer as apart from the way you feel, there may be no available places at this other school, so it would be worth asking your parents to enquire first before you get your hopes up. If you are going into sixth form, then you may be given the option to transfer and apply to this other school, so I would also make enquiries about this. You don't say how long you have been feeling like this, but sometimes things can turn around in a day, and you can make a friend or two from people you have never really connected with before. Joining after school or lunchtime groups may help here. As far as your weekends go, if you have any particular interests joining particular groups may also help broaden your social circle - it only takes one good conversation to make a new friend.
