Nice day outside

It s a beautiful day outside and I am fighting my self not to come in and lay down on the couch because my anxiety and O.C.D. is kicking up.  My friends don't understand how I feel on the inside.  They say I look great and happy.  Which is a far cry on how I feel on the inside.  They say don't focus on how you feel and just get busy but I don't know how to do that.  I feel like crying but the tears won't come  I am tired of feeling this way.  Can anyone help?
