Removing worry from one’s life isn’t something that has to be done alone, or with help for the matter; however it is much easier with the help of a friend or family member.
Trying to tackle worry and anxiety can be a complicated task, and communicating your decision to overcome it with someone can provide new insights and can keep your life light, especially when you are dealing with the heavier things that cause you worry.
When someone knows what you are attempting and going through, they can help provide the time and space to listen, and maybe some additional resources you may not have thought of.
If you choose to overcome worrying without family/friend assistance, there are many online forums for people that can communicate remotely, and this can still provide new insights and philosophies.
There are many pieces of literature on the subject, and those can provide solutions that do not require any interfacing with another person, which can cause additional anxiety.
The point is, to find the many resources that are available, use them, implement them, and remain true to your task.
