Feeling guilty for being happy working!!

I have the option to be a stay at home but I love working with my husband! It’s really exciting work and I feel a sense of purpose outside of my darling 15 month old son. I’m happier, too. I feel guilty though. When I could be at home with him all day he’s with caretakers 8-9 hours while I work supporting my husband’s business. I tried being a stay at home and I was depressed. Not because I don’t live my son. I am obsessed with him!! But because i find so much happiness in the work I do! But I feel guilty for being so happy outside of the home. I feel like I should be home cleaning and cooking for the family. Thoughts? I don’t want him to grow up feeling neglected. Btw, my son gets 100% of my attention in the mornings, evenings and weekends and gets so many cuddles and kisses even when he pushes me away 😛
