extreme separation anxiety

Lauren • 32 year old from Herefordshire. Pregnant with baby #2
I'm 24 weeks pregnant with baby #2 and I'm having crazy separation anxiety with my husband. He's going away for 5 days with work which I know sounds like no time at all but I'm so terrified that something could happen with his plane or train. I always miss him when he's away but last night I sobbed like a baby because I'm going to miss him so much. Has anyone else felt like  this?
