Where to go from here?

These last few years have been something else. I feel like when I start getting a handle on thing's something happens and it's all a mess again. Satan is the worst. Not only does he get into my head but he likes to play games with me. Because of a mistake I made he is not letting me forget it and has been working extra hard on me to give in and let him win. He is so sneaky and deceiving that if I'm not on guard about thing's going on he gets the best of me. He uses one thing to get to another thing then to another and another. For the past 2 1/2 weeks I could feel thing's changing and not for the good. I could feel Satan poking just a little at a time and putting thoughts like, I'm alone, no one cares, I'm not good enough, I don't deserve anything good, etc. Having those thoughts in my head and increasing every day isn't good because I start feeling down and depressed which leads to not caring and lowering my guard. Because he's so sneaky and I was not thinking the right way I ended up doing something that has hurt me and caused me to start doubting everything I have been taught about the church. After what I did I immediately started trying to make it better and putting my guard back up but I obviously didn't get it up fast enough because I started wondering if the church was really even true. I had a time not to long ago that I had to make the choice to stay going to church or give it up but I never once doubting the truth of it. So why now? Why after everything that I went through and fought to turn my life around and be better would I doubt? I continued to pray and I more earnestly started studying topics to try and know, really know that the church is true and that I'm doing the right thing. The doubting and with what happened recently have made the feeling's of unworthy, not good enough, can't do anything right, can't win for trying that much more worse. Because I've doubted I feel like I can't step foot in the temple because why would I be going there when I'm unsure about the church. It's such an embarrassing thing to mess up, even a little, after I've been trying so hard to be good and do the right thing but to doubt the truthfulness of the gospel, that's awful. It's so hard to even think about what people are going to say and the thing's that I'm going to get told and what not. I feel like no matter how hard I try it's never good enough and never will be. I know that my faith is lacking a ton and I have to rebuild that up. I feel that the only thing that keeps me doing thing's like, going to church, reading/studying my scriptures and saying my prayers is hope, hope that I will feel something, that I will receive and answer, that I will know that I am loved and that I'm doing good and that it's all worth something. I hope that one day I will be strong enough to not let my emotions get the best of me and that I wont keep falling in this struggle that I'm facing. I wish that I didn't worry about how much I've disappointed people or how disappointed their going to be. I really wish sometimes I could just crawl in a hole and not face anyone. But........I know that that's not possible so I have to be strong and face it head on and hope that I feel love instead or disappointment.
