A very warm welcome from me too. Is there any possibility that you could share the job with another person? It always seems less daunting if there are two of you .....do what you feel you are able to without feeling guilty about what you are not ready to face. But dont let fear or lack of confidence get in the way. It sounds as if it appeals to you but you are nervous, which is very very natural. At the end of the day only you can decide. Good Luck with what you do and Well done you for getting your son through all the problems... I hope everything works out well for him from now on
