I have been arrested and questioned in regards to setting up a fake id on a /dating website.?

The person the id was about was my husband's ex wife. The police told me they traced it back to an IP address at my work. I'm not sure if the IP is my actually computer I always use or just a company IP. I was questioned but not charged. I cant eat, sleep etc, my husband and I are on the verge of splitting up over this. I have contacted a solicitor and they told me I just have to wait now, wait and see if Im sent a summons for charges. I'm scared, I've never been in trouble with police before, have no prior record etc, have been in my job for past 16 years, I may lose my job if charged because they say the fake id was set up from work computer. Please help...what could happen to me if charged and found guilty? I have two teenage children I care for.
