Decisions are hard to make

I just found out that it is so hard to make a decision is just so hard!!!Just can't make up my mind that i should change school anot??? if i change school, i will miss all my friends and also the fun and trouble that i have been through but if i change i can pay more attention in my studies and also getting better grades because sri cempaka is more to studying not like hartamas gamble,play and play a fool every single day with my gila friends. but however my decision is, i hope that i can maintain my relationship with my friends even though i change school. Even i do have loads of friends in cempaka but it just won't be the same as my friends that i spend everyday and most of the time with that we have done so many fun and also maked so much trouble with like royce,ho lee,crystal and the main 1 choo. Also just met a 2 new friends like amirul and alice this year that are super fun. So what can i do to make the right decision that will benefit me and also my studying but most important my good friends. Please god help me in this one!!!!!!!
