My Church ministry and my leader need help please?

ok I got into an argument with my leader and cannot open my group and the reason why is because I finally told him that Joel Osteen is a false prophet of God and note mainly because he has gone against the word of God preaching only motivation and saying that religion like mormons is true and that their is no way to tell whether or not their is only one way then at the same time saying that he is(Jesus) while Jesus preached Gods word,not only that he preached more about hell then heaven and so forth,what im getting to is that I could not just stand their and let other people be deceived by this man,and espically my leader and so many other people who listhen more to the pastor then the word of God like come on!however what I am asking is that now,while I cannot just say I am perfect I notice that my leader kept talking about Osteens fruit yes it is large but you cant just go by that,even the devil disguises himself as an angel of light,now because I want someone to help me I want to put every detail my leader said dont judge with hypocrisy and to stop critisizing him when I was trying to expose him like we should because before he came I was about to pray because I didnt do it anymore for 2-3 weeks also I told him right before the argument at the time I felt almost no desire until I saw a preacher Paul Washer talk about praying and I felt like I have to do this now but my leader came and used it against me but I told him this now even when I did pray to God I knew that Joel was wrong but I noticed that so many leaders at my church do listhen to this man read what he says but i know its wrong in Gods word from the Bible,afterwards he says I need another Exodus which is a 3 day retreat to encounter God at my Church (it is 180 right now to pay for the buses and food and henceforth)and I have already went to one now after im almost done and went to my launch another thing cost lower amount and did my leadership class's he said I should go again I said what I need to do is go to Christ right now yes I was being a hypocrite yes since i havent prayed and ive been telling myself that I kept my Gods commands and i wanted to pray I couldnt because their was a desire to not want God and I felt fake and embassed to go to God I was tired of going to Church letting some of my school grades go down so I could go on (note this is when I went to class in church on modays right now no)monday tuesday,wenesday,friday and sunday for the whole day and i got exausted and my mom got mad at me for going to much to Church she left and turned mormon but I would not let her and told her the Gospel even when she got mad at me I continued for months now she goes to a church that is Christian and I am happy she goes because she is growing now,and now I dont know my leader says why dont you listhen to me since we are suppose to submit in Hebrew if im not mistaken,but if what I was trying to do was tell the truth am I wrong for that?and please help, I am not going to leave my church God helped me increase in it but most of the times I felt nothing in church,until one day I did but at my launch when I finally felt an encounter because at the time everyone except a couple of people 2 actually stayed by my side while everyone else didnt want to be by me and help me or anything but because of it I went to God and he touched me made me feel so much better I was at peace and felt God but now everyone is rebuking me for telling the truth but right now I believe if I am telling the truth but everyone thinks im going crazy because of it and im talking bad about osteen and everything but what i say comes from the Bible am I wrong for this telling it to people who listhen to this man? if you want to dicuss i,ll send mail to you please help if need correction as well and also I was willing to throw everything i've worked for spent money on to be a leader at my church and open a group just to telll the truth(but I would like to hear if you would want to say something) (I am 14 still in high school)
