Raquel Anne 

I have been with services for a number of years, initially as an client with a variety of mental and addiction issues. They have supported me with all of these issues and supported me within my transition with changing from male to female all the way through the process. I initially started volunteering to give something back to the charity, I have developed so much more, as I am clean and sober, a very social and confident person who is positively growing from strength to strength. I'm currently enrolled on various course to advance my career  which is leading to many new opportunities.

My life is very busy and exciting within all areas of my life. My volunteering role involves many new and exciting challenges with co-facilitating and working with people of all ages and from all backgrounds. social life involves coffees and meals with many friends and I enjoy spending a lot of time supporting my family and being with them. I love going to the gym, collecting and watching films as well as going on walks and away with close friends.
