How to be of service if circumstances don't allow it?

[Starflower]

Thank you all SO much for your responses, they have helped me massively in my understanding. I have another question but not sure if I should ask here or open a new thread, I will try here first and see - someone stated that being of service to others can be how we affect those closest to us - I have more or less cut contact with two members in my family due to how they made me feel (one was very negative/selfish and the other was using me for money and only seemed to contact me for this reason) I have forgiven these people but I'm now wondering if I should actually be contacting these people and trying to be of service to them? What worries me is how it may affect me as a result. I have limited contact with my mum for the same reason, I keep her at a distance due to her negativity - is this wrong?
