We are TTC but...

I'm 35 n hubby is 40 we r TTC n my anxiety level is kind of high n I feel that sex will calm it down but my hubby is tired n I want more sex how can I help him get more energy to keep going, he works hard too, I feel that maybe we r just working too hard at it, should I give him a break? How can I get my anxiety down n don't say exercise cuz is not working either I feel I need a drink to take the edge off. Any thoughts?
