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 of us being a support to others.
People may often find practical support easier and although the practical side is the easiest form of support, it is also the more time consuming.
With emotional support we should be more able to act as a support to other people, later on. With work on ourselves, being supportive is something we could all do.
Just because we have never had support, doesn’t mean we can’t act as a support. It may just take us longer to work through the logistics of how we can be a support.
