You can do this - and you can do it well!
Keep coming in here for support, and maybe contact your local health service for a single mums group/young mums group ( i think they class under 25 as 'young' - go figure! ).

It might be worth going to Centrelink to see what support you can get financially and they also might be able to hook you up with any counselling you feel you may need.

Good luck - you are more capable then you know
