Don't know what to do ...

I'm basically loosing it ... There is sooo much pressure on me right now and i can't handle . I pray constantly for the Lord to take it all away ....I mean i'm trying to be strong for Josh , and my mom , and help with everything and ... i'm only one person ! i can't do this . I mean i'm just a 16 year old girl .... Joshua isn't doing to good . He randomly snaps . I'm afraid to say something that will make him mad . I'm trying to be a good girlfriend and be supportive but it's kinda hard to understand something that ....that you can't relate too . Like i don't know what to say when he talks to me about the situation . I pray for Him to give me the strength and words to say to him . Josh says he doesn't like talking to me about his problems cause he doesn't want to put any more stress on me , and how i can't relate to a guy . So what if i may not be able to relate . At least let me try to . Even if i can't relate i'll be able to listen still and TRY to help get it off his chest . I don't know . I guess i'm just rambling now ....
