Even though I think she could try harder to integrate, it’s clear they just want her gone at this point which doesn’t make it any easier. She never even mentions going back, but they constantly jump to that whenever there’s a problem rather than trying to find a solution. They seemed to really embrace her with the wedding and all but either it was for all for show or she’s really worn her welcome. TJ looks so fed up but that’s what he gets for deceiving her honestly.
I am quite familiar with depression. I am also familiar with the various ways one can attempt to deal with it. I agree that TJ’s family is terrible towards her. Her best bet would probably be just to leave; but failing that or in the meantime, she can either stay locked away or try to do something. Didn’t say that it was easy - but it’s necessary.
