Am I too needy?

Merry Christmas! Probably like a lot of others I'm not too good this time of year. I've lost both my parents and am a single parent to 2 teenagers. I have 3 half sistes and a half brother. My brother is the only one who calls me or I call him. I haven't seen him in years and years,the same with 2 of my half sisters and the last one I saw 3 years ago when my mum died. I feel so on my own. They have sent Xmas cards but not one of them asks how I am(I did on their cards). I just feel very sick. They really don't care very much.
My husband left me for another woman when my kids were little. He had had enough of me. I don't hear from his family at all even though I'm the mother of his children.
All I hear is people saying how many people they are having for Xmas. I am happy I'm with my two children,there won't be any stress but then they are off to their dads Xmas day tea time for a week.
I'm now worrying that I'm too needy,that I shouldn't let any of this bother me. But it does,hugely.
I also have a chronic illness called fibromyalgia which has had an immense effect on my life. I did have my own business but had to close it down 4 years ago and haven't been able to work since. I feel unwell every single day,it's very very hard but I try and keep going for my kids sake. I know what's its like to loose someone close and I could never put them though that.
I find the main thing that helps is to get tough and find that inner strength. Stuff them all,but sometimes it's too hard and the realisation that I'm very much on my own is so painful.

I don't think you're too needy. I think you're a lonely human being with normal wants and needs.

having needs and being needy are two different things. You do not sound needy at all.

So what do I do to feel better,I feel like this is it for me. Unable to have a relationship because of my illness,unable to reach out to my family because I'm too damned scared of the rejection.
