You can never be connected to those you love all the time. I'm sure you love certain relatives and yet don't think of them all the time and feel connected to them all of the time. I suggest giving yourself a break and remind your self to connect with yourself first before concerning yourself with connecting with others.
How you are feeling is how I burned out, until I decided to switch it around. I would connect in those moments when you rediscover how wonderful they are and decide to be delighted and filled with joy then. It seems to be a good way to live and make love abundant in my life anyway.
Guilt and fear do nothing for spreading love in my experience.
