Well first of all: Try it. Write applications, (maybe) get rejected - that‘s life and that‘s rhe way it always will be. But at least you tried.
Maybe you fail the assessement...I and most others failed some of them. No big deal to be honest. Annoying, yes. But you‘ll get another chance somewhere else. Maybe also think outside of the box: Get an instructor rating do some instructing...cheaper way to get paid for flying than trying to get in an airline cockpit right away. Or if you‘re worried about the ecological impact: Why don‘t you try to work at an airport? Not checking in paxes, but maybe as a (for example) dispatcher? Ramp agent? Gets you working and you‘re kind of in the industry...
