It's so hard

This sleeping issue.  I try to remain positive and calm but its just so hard. I dose off and one of the many people in the house makes a noise and that's it, wide awake! I just want the house back to silence.  I am anxious about work.  I didn't sleep until 4am last night.  How will I go to work if that happens in a few weeks time? I feel my anxiety rising but there is nothing I can do.  I don't even have my lamp to read by as its been taken for one of the visitors.  I long to sleep.  I long to run away and just have a few days and nights by myself to rest and go to sleep. I want the people downstairs to stop talking. I want someone to take this insomnia away from me.  It's become a habit and now somehow I have to break it but whilst the thing that caused it to form is still here and my main coping strategy, to get up and move to a different room, is no longer available.  Ideas welcome!
