Wanting to do more ??? Personal crisis atm

Tried to word this to Ben today but struggled trying to make sense of my thoughts. I'm hoping maybe if I voice my thoughts at the end of my presentation people may be able to offer some advice?
Things floating around my head at the moment:

- Feeling guilty, I'm very lucky to be doing what I love so I feel guilty when I take time off or stress, its a privilege to be doing what I do. (I know this is silly but I can't help it)

- Wanting to make a change? Sometimes it feels silly/selfish when I'm stressing out over an image, when there are people actually out there making a difference to issues around the world?

- I'm very engaged in the issues around the world at the moment, and very passionate about social justice, human rights, refugee crisis, climate change, veganism, etc etc, but other than reading and posting about it and going to marches, what am I actually doing to help? I think I need to volunteer or do some practical help? I've looked into volunteering in local foodbanks but they don't need any more volunteers at the moment. My auntie runs a volunteer centre where she lives in La Paz in Bolivia which helps working women with childcare and other social issues, as well as a local animal shelter, I'm definitely interested in going over there for a while to help out. She wants me to go and do some murals with the kids over there for the centres which would be amazing.
I could also try and combine the two and make some charity prints or make my work seem more relevant to these issues I'm passionate about?

- I think all in all I want to make a change / being more selfless?? I've been thinking recently about teaching. My mums a primary school teacher and I'm definitely not cut out for that but I'm interested in teaching at university level. Tutors really have changed my life and way of thinking and I would like to give back and be engaged in that somehow?

- I don't really know what I'm trying to say here, I think I'm just frustrated at the moment. I'm very worried about the state of the world and sometimes I just feel like I need to be putting more energy in tackling these problems rather than just being angry about them.
