Hi, sorry I’m a bit pushed for time at the mo but…
Adult ADD UK has a really good section on how to get help in the UK.
Unfortunately it is usually extremely slow (years) and can be a tough fight to get in a room with the right doctor. You need to gather all the info and push your case firmly yet politely.
Many just can’t wait that long so turn to the private sector, which is very fast. But then you need to transistion back to the NHS… Sometimes this can be quite easy, but sometimes not !
Medication – wow big questions… There is some great info on this site about meds (mostly the same in the UK) The stuff in the webinars is great (you might need to watch it more than once though) 
Improvement mainly comes from learning, accepting and adjusting – meds can really help this – (emotionally very hard, so take care)
You are VERY lucky to have a family (many of us have nobody) that will help you through, and make it all worthwhile 
Alcohol + ADHD is bad news, it can easily destroy everything – withdrawl is horrid and dangerous too 
If you feel up to it, maybe make a start on the books, they will help a lot.
If you are down in London anytime, the Central London Support Group is the 1st Tuesday of the month 7-9pm at Costa Coffee in Argyll Street, round the corner from Oxford Circus tube station. The strange but nice people at the back 
Some decamp to the pub over the road, after the coffee. Nothing formal, just chat, try to help each other and have a laugh.
Take Care 😉
