It is great if you have people who can give you support, but not everyone can be a support. Our experiences are usually the catalyst in us being able to support others.
People often find practical support easier and although the practical side is the easiest form of support, it is also the more time consuming. That said, others being able to help us out in practical ways, will help alleviate some of our stress.
With emotionally support we will be more able to act as a support to other people, later on. With work on ourselves, being supportive is something we can all do.
And just because you’ve never had support, doesn’t mean you can’t give support. It may take you longer to work through the logistics of how you can be a support.
