What can I do to block out mental pain?

[Plantlover]

I won't be having contact with my eldest child. It's for the best but it hurts so much.

What I can I do to stop hurting so much?

Maybe accept and experience the pain rather than blocking it out? As you know it’s for the best, it’ll probably get better over time.

I have another child to look after so it's difficult because I would be visibly upset etc.
