Hiya there
I think most people here will identify in some way with your post and being 'out in the dry desert' as it were is never a pleasant experience you can be sure that the Lord has not changed, today , tommorow..or ever.
It has been my experience that faith carries us through these periods when the Lord refines us in ways that we didn't even dream were possible. and that the 'joyful, happy, easy' times are a oasis a time for us to reflect and enjoy the work the Lord has done through those building times, I no longer take them for granted, but after each one my patience and faith and trust grows. These times are so that we can know ourselves for our benefit, not so that he who knew us even before we were born can know us.
I do hope and prayer that you will soon come to a resting time, where once again your heart is settled and safe, and using what the Lord has made you, you once again hold your hand out to someone and say 'come taste..how good the Lord is'
Bless you
