I've been diagnosed with depression and anxiety, at my worst I was stuck in bed for days. This will be a long one so I apologise in advance.

I'm on therapy (usually once a month) and was previously on mild anti-depressants. The therapy has been useful and I intend to continue with it. I hate the medication but I'm not sure if I should go back on it or not.

Anyway I'm feeling overwhelmed by everything recently, even the most mild things such as:

\- Broken things around the house (have a big pile of things I need to do)

\- Neighbors yelling and carrying on at each other.

\- Dogs barking and cats coming into my yard where I have a pond. And a sick fish I own (my fish mean a lot to me as strange as that sounds.)

Really things that shouldn't upset me but recently I've been feeling a lot of pressure.

My mother just sent my younger sister (16) to live with me as she was having heated arguments with my nan (my nan is a nasty lady who lives with my mother). My mum owns half the house with my nan and doesn't want to leave or give up a share. Regardless, my sister has a history of depression/anxiety/ptsd from being around abusive people such as my nan (and her father who hit her). 

She is a nice enough kid but all she does is stay in her room, I've only had her for two days (not long right?) and she exhibits a lot of concerning behavior including:

\- Does not brush her teeth or have a shower unless I push her to do it.

\- Eats small amounts of food infrequently.

\- Refuses to leave her room unless I really push her to go for a walk with me. Mostly messes around on social media and gets upset when someone online is mean to her (she has no friends in real life). Also fixates on identity and lgbt+ related issues.

\- Randomly initiates strange / inappropriate conversations about serial killer documentaries that she has watched. Is suspicious and negative of random people. Will ask questions like "do you think that person hits their dog?" (when we met a family with their dog in the park). Any friendly interaction from a stranger is viewed negatively.

\- Generally just looks miserable and says she feels like throwing up occasionally. I try to do things with her but she is highly unresponsive like a zombie. She doesn't go to school or anything. Behaviorally she is very odd. Sometimes enters the room and will laugh when she surprises me, it feels manic.

Prior to my sister's arrival I asked if therapy was in place but apparently she is between therapists, my mum wanted to send my sister here so my sister can have a "break" in a safe place. My mother told me that my sister is doing well and wont cause problems but I don't feel this is the case either. I don't want to deny my sister a safe place but I already feel rather uncomfortable and overwhelmed. In terms of tools all I have is my intuition on helping her form healthy routines and a box of prozac  that my sister was prescribed.

I'm just overwhelmed and don't know what to do on top of my own issues. Maybe dramatic but a part of me feels like just disappearing of the grid (or dying) to escape the things that worry me but it isn't realistic.

Thanks for reading about my problems (it helps to type things out) I hope you're doing well too.
