3 Year Old Separation Anxiety

My son Turned 3 this last September.. He is an over all great kid.. He is very well behaved. and polite. He loves to share and be around others. My problem started a few weeks ago with him Wanting to see me or be near me.. It doesn't matter where we are.. I have to be in his sight at all times.. Even when we are home.. He is deathly afraid that I am going to leave him.. I can't go to that bath room by myself or walk down the hall way.. I can't go in my room with out him chasing after me screaming.. My husband works all day and I'm a stay at home mother.. My nephew moved in a few weeks ago. I don't know if it's because of change. But he is use to people around all the time. Mostly my family. He had Separation Anxiety before and he grew out of it.. But this time it's bad.. I don't know what to do about it and I don't want to make him feel like it's his fault when I am upset. I can't take a step back or have time for myself to think. He has to be near me. I want to have him in Pre-School but I am afraid he wont be excepted because of his Separation Anxiety. I just wanted to know what I can do or if there are any programs that me and my son can take to help him.. I don't want him to miss out on pre-school and learning his social skills and developement with others.. Please help.. Thanks Heather

Social skills can be developed at the local library, playground, church activities, etc.  It sounds as if he is just not ready to be separated from you.  Could you find a "Mother and Child" activity where he plays with other children and you get to visit with other mothers?  Ask the other mothers in your neighbourhood if they have any ideas?  Or, could you have playdates in your home and also invite the other mothers?  There are several books on anxiety that can be found on the internet, bookstore or local library.
