1 year old attachment

My son is 14 months I signed up for a gym with a daycare and he cries every time I leave him! The longest I got to work out was 45min. And I was happy with that. But now it just gets shorter and shorter. Today was 10 MINUTES before they called me to get him. How do I get him to not cry so much? It makes me sad.

How attachment has also kept me from going back to school/work. Nobody will watch him for me 😢 old what to do
