You're depleted and need time to recover before you try helping again. This is a perfect case of "secure your own mask before assisting others".

Go be with friends. Touch some grass. Do some art. Go visit a garden or plant something.

If you feel up to it, look into volunteering we local food banks or animal shelters.

On a larger scale, build a digital lifeboat and de-google/apple/fb. Form privacy cooperatives with your family and friends (whoever is the techiest runs a server for the cooperative and you all share a private cloud). This can act as a filter and a support group if managed well.
