<human>: Can you give me the gist of the text in a nutshell?

* Painting a picture:

We don't really speak to our extended family anymore. They do/did lots of drugs, are extremely rude and disrespectful at group gatherings, my cousin hit on my girlfriend a family reunion, etc...

What's so upsetting about all of this is that my immediate family (mom, sister, and myself) have been extremely close all of our lives. We have never abandoned each other since my extended family has taught us how not to be.

* Current situation:

My sister hasn't spoken to my mom or myself in over 2 months. I'm very upset and worried for her (she was molested as a child by a fellow church member -- we're all atheists now except my mom) because of her past. I've always been her big brother. I've always been there for her and so has my mom. 

* What I think:

My sister seems to be upset because I was laid off work and am currently relying on unemployment to make ends meet and that my mom MIGHT lose her job because her union doesn't seem to want to represent the workers that are being mistreated (my mom stands up for herself and her co-workers as opposed to many others). I'm currently working a side business that is beginning to generate enough revenue to make my full-time job in the near future and the possibility that my mom will get fired is relatively low. 

These tiny bumps in the road, that we all seem to go through, seem to devastate her.I know my sister is really stressed and worried for us, but simply not communicating with your family (my sister didn't even bother to call my mom on Mother's day) is not the way to go. Reddit, how can I fix this!! I'm a guy. Tell me what to do and I'll do it! Thanks in advance and sorry for the long post.
<bot>: My sister hasn't communicated with either my mom or myself (her brother) in over 2 months. I know she is physically safe, but I very much worry about her well-being and this is tearing my mom apart.
