How to deal with anxiety of being alone though.

I am not sure why recently I don't like it when I am alone though. I get anxious ya. How can I feel less like this. Any advice would be cool ya. Thanks.

I am new to the forum and recently submitted my first post explaining my situation and I too suffer from anxiety related to being alone. This seems to have manifested over this past weekend when my mother came for a visit and stayed for two weeks. When she was here the first week, my anxiety was still pretty bad and I was struggling a lot to eat and function day to day (I had only been back on the Lexapro for about 2 weeks). The second week that she was here with me, I felt much better, I was eating 3 meals a day, running errands without even thinking about my panic; I truly thought I was getting better now that I was back on my Lexapro after a 2 month break. I was wrong, and now I am more discouraged than ever. The day after she got on the plane to return home, I lost a lot of the progress that I thought I had made. I feel as though I have regressed (although the depression I had is better and I am still sleeping okay, which is an improvement from when I was off the Lexapro totally). I now have panic attacks throughout the day and cannot concentrate at work. When I am home alone, my panic worsens greatly. I am to the point where I have called my cousin over to spend the night with me when my fiancé works overnight shifts so I am not alone. I hope that as my increased dosage of Lexapro starts to work that this irrational fear of being alone goes away too...I know I cannot rely on people to stay with me forever. I took my first dose of Lexapro 15 mg today, with the advice of my doctor.
