Trying to Get Through

I've been telling myself and everyone around me that I'm doing good and I know that thing's will work out some how but today has not been on of those days that I believe that. I don't want people to feel sorry for me or tell me that things are going to be ok. I know in the end thing's will be ok but when I feel like everything around me is caving in, I'm not good enough, and I've become a failure it's hard to see the light at the end of the tunnel. Maybe part of it is that I'm feeling sorry for myself and I know that I need to get out of that cause it doesn't do me any good. When thing's around you never go right and it's hard to see anything good what do you do?! I know I need to be better at somethings but if this is what i have to deal with I wish that I never came home from my mission. It's become such a hard thing and no one understands what I'm feeling and going through. I don't even know how to explain how I truly feel so what would be the point of trying to talk about it. I guess this is just my way to vent a little and hope that by doing so I''ll feel better and can move on and hopefully see a light at the end of the tunnel.
 I have been dealing with some emotional problems and am feeling like I'm becoming bitter about thing's and towards some people. How do I stop that? Here's the problem, I think it might help to talk to someone but I can't bring myself to talking to someone that could possible help or know how I feel because I don't want to be a bother or burden anyone with my problems. So I've just keep most of it to myself and try to figure it out on my own. I pray and ask for guidance and direction but feel like I'm not getting anything. I don't like not knowing what to do or that nothing seems to be working out in my favor. I still tell myself that everything is going to be ok but I'm having a hard time believing it right now.
 Tomorrow will be another day and I hope that it will be a better one then today!
