Hi I often feel I want to do this too but having spent 11 months living like that in 1976 I was done in by November. I was a fit teen then. Recently spent 11 days on minimal foraging diet lost half a stone in that time and there is plenty out there right now to forage. Can you preserve any food you may collect now? Have you the ability to bottle or dry berries. Make jerky or fruit leather and store it so it won't spoil? It's hard work and I'm flat out all day preserving and foraging this time of year to put stores in my cupboards. I know my area well (18 yrs) some years there is a lack of things you might be relying on to feed yourself. If you are thinking of buying basic stores flour rice oil sugar honey salt pepper herbs stock cubes tea or coffee are minimum look at what the pioneers in America had to take by law to go across the country in Thier wagons. It's a lot!winter is rough as he'll in the wild. Especially on your own. It plays havoc with the mind if you are not prepared.believe me I know. Just wanting to escape is understandable. I guess that goes through my mind most days if I'm honest.please plan plan plan and research research research. Hunger and wet and cold do funny things to the mind when you are alone. Think hard before you take the plunge and make sure you have a back up plan if it goes wrong on you. Take care and best of luck.
