Neck lump biopsy

Hi, about 7 months ago I found lump in neck, fast forward to now have had FNA - inconclusive, followed by core biopsy which initial path lab referred to specialist lymphoma unit for 2nd opinion. Received phone call earlier this week asking me to go in see them tomorrow. Have tried to carry on as normal but am pretty scared at mo. Oddly my partner had been very distant, & cold since the phone call. It's like he is sulking but won't say why? Feeling very out of kilter at present. Has anyone else had this sort of experience.
