Got Laid Off Today

Not sure how to describe the feeling of loosing your job. I felt a bit of heartache like I lost a part of me. 10 years is a long time to work somewhere and then leave it behind. I'm pretty sure it's all for the best, yet its definatly a big change. I feel free, yet to do what I'm not sure. Should I chase my dreams or find the quickest way to another job? Friends are telling me "I'm sorry", which makes me feel I'm sorry. Most of all I think it must take some time to sink in, as it's too much all at once.
