((hugz)) Take enough time 'off' and have some 'life' iRL as well... Go for a walk, talk to people in RL, hug someone...

It's really hard to wish to help everyone, and you can't, cause you're just one person... It's good that there are many helpful people online and that others can help if one can't... At least that is what I tell myself and it helps somehow
