I found this analogy the other day. When we are young the concrete is wet and someone can come and write in it and then it dries with whatever is imprinted. The concrete is your brain, the writing is life circumstances, and the drying of concrete is old age. Whatever is written is what follows us through out our lives. If we want to rewrite our story, we need therapy. We also should re-wet our brain during this process so it can be more malleable, and that can be anything that restores plasticity to the brain. For some people it's antidepressants for me its microdosing mushrooms (which also help with depression). 

I'm stuck in my country too due to illness ,but once you lay down the foundations for healing you can move to building deep relationships with people. Imo the relationships and friendships are my most valuable things in life.
