MotherSeeker I hope you find some help with your problems.
I think you might find much better help by seeking someone in real life than online. Finding a 'mum' may be hard but you may find a 'mentor' as someone easier for you to source.
For more info you could take a look at.....
This article.... "The idea of mentoring holds great appeal - it conjures up a positive way of bridging boundaries between generations and harks back to notions of large extended families and friendly neighbourhoods within which young people and elders could establish common ground."

Depending where you live there may well be a mentoring scheme you can join.
I found several for London but they are really specific for specific groups of people and only you know what you need.
This page offers a very good explanation of what a mentor is...

Depending where you are in the country you may well find a scheme that is of use. The only thing is the websites all seem to be geared towards talking to those who will volunteer to mentor so you may need to call someone at these places and see how you can join a scheme.
Loads of places run them...
EG....
Bolton
"Working alongside partnership agencies such as Bolton Council’s Children’s Services, the mentoring service works with young people aged 8-21 years old, offering them support and guidance from a one-to-one mentor who helps them overcome issues they may be experiencing or a goal they would like to achieve, based on an individual action plan."

Manchester
"At ReachOut we aim to develop character and improve competence in our mentees to give them the skills they need for the future. "

Oxfordshire
The Early Intervention Service provides support for vulnerable children, young people and their families. We are currently recruiting volunteers to act as mentors to disaffected young people in Oxfordshire.

It really depends where you are in the country but this may be a way of getting practical support and one-to-one time with someone who is themselves supported and trained.
Good luck.
