Mum going back to work

Hi, I'm a mum of a 17 year old who has ASC, I have not worked for the last 11 years and start a part time job tomorrow.

I am really struggling to leave my son as I have been at home and supported him the past 11 years.

Thankfully he has become more independent and is in his last year at college,the problem is when anything goes not to plan for him he goes into panic mode and all rational thinking goes out of the window.

My fear is I won't be there in case this happens, but I know I need to let him try and be more independent and learn to deal with  situations .

My heart says stay at home in case he needs me , my head says go to work and let him be more independent.

Anyone  out there that has been in a similar situation 

Thanks
