I work in Mental Health and Disability so I have a rough idea of the circumstances you are coming from as I deal with clients that have similar issues as your mother. Each and every case is unique with different circumstances.
I do want to say this though, try not to let the emotional and/or physical abuse your mother has been giving you change your outlook on yourself.
Things may seem rough at the moment but try to look at it as a positive. Now that you have sorted your herps in the meantime, you can start looking for a place of your own and move on to the next step in life with freedom away from abuse.
Hopefully your uncle can help you with this too, but there are many community services that can help you also in this situation when you are looking for accommodation.
In the short term, Dept or housing may be able to put you up in a motel or shelter if you have no present accommodation. They can also give you what is called a 'tenancy guarantee', which is a guarantee to any real estate that they will pay an extra $1500 on top of your bond upon exiting if your bond does not cover damages (not saying there will be, but its an added incentive to a landlord) You can also get a bond start loan from them that will cover one week of your 2 weeks in advance and 3 weeks of your bond. You will need to pay that back to them in installments over 12 months
Going to the herp society meetings is a great idea, you can meet people who are like minded and most you will find to be very supportive. A lot of the time we hear about the bad people within the hobby but there are plenty of good ones too
You have friends as you have seen in this thread
if you need to talk to someone there are plenty of people willing to listen.
