Dear Lyndsey
I am sorry to hear about the tragic events of losing your loved ones in such a short space of time from illnesses and alcoholism. It must be so difficult to have to watch your sister struggling with same addiction to alcohol as your brother.
Should you wish to speak to someone who has the same experience of what you are going through with your sister, I work for a charity called The Icarus Trust. The charity was set up to support families and friends of addicts.
We have experienced and trained volunteers called Family Friends who you could talk to for support. It is a free service and you can contact us by email on help@icarustrust.org or visit our website http://www.icarustrust.org
I wish you all the best and hope that you are able to get the help and support you need.
Charlotte
