She's 47 &amp; became a stay at home mum to look after me &amp; my sisters. We're all older now &amp; she's still a stay at home mom but is fully capable of getting a job but hasn't. Because of this, my parents have financial problems. My mom basically stays home all day watching TV, going on her phone &amp; she sleeps a lot. She only ever gets out to go grocery shopping &amp; to run errands etc. She basically has no friends &amp; no social life, the only person she talks to besides me, my dad &amp; my sisters is her mom, she doesn't really talk to her dad &amp; siblings, she used to be closer with them. She always gets into arguments with my dad &amp; sister about stupid shit &amp; she is very easily annoyed. She switches moods a lot &amp; if you say something negative about her or criticize something she's done she'll immediately change the subject. She also stalks people on social media a lot. One time me, my mum &amp; my sister were driving back home on a major highway in the dark &amp; my mum hate's driving on major highways &amp; in the dark &amp; she completely lost her shit (it was kinda scary) &amp; started yelling &amp; kind of crying at sister &amp; blaming this situation on her (it wasn't my sister's fault) &amp; the moment we got to our home town she was fine &amp; brought us pizza &amp; started laughing at what happened. I'm assuming she has some level of depression maybe, I'm just asking what y'all thoughts &amp; opinions are? (sorry about the bad grammar)
