Near Hell week feeling:(

Today have to send him in early at 6.30pm.. But I dun wan to... Cause this time round is in but have to wait till next month dun Noe when then he will be out... Hell week is the one who make me be so sad:( I Noe he also dun like but I just can't let him noe that I'm not happy because he's going in and have to went through the hell week thing... What can I do now?? Beside sending him and what??? I really dun hate feeling like this.. Last time when he went for field camp, I ever ask his buddy what she did when her boyfriend was in field camp.. She told me a few thing, and also she said dun let your mood affect him.. As his stead, You should support him and stay by his side to encourage him... So now I really cannot let him noe how I feel:( but how??? I can't hide my feeling towards him..
