Phone calls

Today I made phone calls.  My husband thinks I have closed myself up to the world since I stopped smoking.  He says I need to start talking to people or else get out of the house because he thinks I am just too depressed.  I guess he's right.  I have secluded myself in this house since I stopped smoking because I don't want to fail.  I think that if for any reason, I visit my dad (he's a chain smoker) I will want to smoke again and I can't take that chance right now.  I don't trust myself.  But I thought I might make a couple of calls and see how mad every one was.  Well out of about 5 calls, I only talked to two people. 
One person was my long time friend, and you know what?  She has wanted some time to herself also, so she really didn't mind that I hadn't called or talked to her.  Everyone else must be pissed off but at least they will see my number on their caller ID. 
I cannot stress enough how long or how important it is to me to keep my quit.  This is not a "hey, I've got nothing better to do" kind of thing.  I made my children a promise.  They didn't ask me to  quit, I made the promise of my own free will, but I don't break promises. 
Is this selfish of me?  I quit drinking this way too.  I couldn't be around people when they were drinking.  It did take a couple of months, but hey, I'm sober 5 years and not missing it one bit, except for a couple of dreams where I was drinking in them.  But hey, if I drink in my dreams, that's not really drinking right? I guess it's like cheating.   Anyway, I am sober, smoke free, but extremely lonely and kind of hating it at the moment.  I hope this goes away.
