I have a few problems , i cant study and I am failing in school, because I have no friends and i think im gay?

Hey there i read your troubles and cant honestly give you an amzing answer but what i can say is that your not on your own these things happen, yes your going through alot of troubles at the moment and you need to relax and try not to put so much on your-self its horrible to have a loved one pass but he is in a better place now and as for your male friend i think its beauitful the way you feel about him but you are young and must really concider how this will affect your life do you talk to this guy and tell him your feelings or do you leave it do you even know if this guy is gay. I speak to you as a guy whom has been in your situation im 23 and went through the motions like you are school is a trying time for anyone but i can sympathise with you trust me being gay matures you so fast and you look at the bigger picture when most people your age you think need to grow up lol! but as i said i dont have all the answers and the only person who can resolve this is you, you have alot on your plate sort of speak and you need to stop worrying about everything as some1 has wrote before if they arnt your friends they are the ones missing out! dont try and live in some1 elses shoes you are you and be proud of who you are look its amazing your parents are spending alot of time on your education and if you dont get the grades so what!!!!! you tried!!! you have one life hun dont waste it on wondering about if's and buts... I personally feel you should have a diary and write down everything in there this will help release alot of the emotions stored away and a new day is a new start time manage what you do so its not all left to the last minuite i wish you all the best and trust me what ever happens you have a friend in god!! best of luck xD x
