Thank you all for the warm welcome, and for the advice

I'm going to try and find a support group and look into speaking to my GP for a referral to counselling, I've already started taking some small steps which have helped a little on my own after reading the forums for a while.
I'm looking forward to talking to you all over time, I've got so many thoughts and feelings going through my head at the moment, I'm scared of hurting my family but excited at the realisation of who I truly am and that it's not too late for me to become this person, I still feel guilty for feeling this way and selfish for wanting to change like maybe I'm making things seem worse for myself than they are.
My family is a mix of liberal and conservative ex-forces people and if my parents find out I could end up homeless (my Dad isn't likely to accept me), I also have a 6 year old Son from a failed relationship who I see weekly and idolises me as his Dad.
Is there anyone who's had experience coming out to a young child, I haven't found much information on the topic as most of my searches find advice for parents who's children are transgender. I'm nowhere near ready to come out to my family yet but I worry about how it might affect him both directly and indirectly (bullying at school), I honestly don't think I can cope keeping up this false persona for years.
Sorry again if this isn't the right place for this, if it's not please could you point me to a more appropriate place to discuss these issues?
Sorry for the rambling, Mez x
