Adversity will change anyone to some degree, but becoming discouraged or experiencing depression does not make you weak. Your situation would test
anyone.
Sometimes the situation we've found ourselves in has dragged us so far down that we need meds to help us get back up, and sometimes those meds need to be tweaked. Some people find therapy helpful. Getting psych care isn't a sign of weakness either. If you start to feel like you are really starting to lose morale, this might be an avenue to pursue, or pursue further.
I'm glad that you haven't given up hope
