Practise being optimistic.
Even if you don't fully believe it just yet, try making your thoughts benefit you, rather than creating further barriers. If there is trouble brewing, you know that making a conscious choice to make it worse isn't going to help. Practise optimism so that it will eventually become habit; make a choice that seeks to improve a situation. At first, it might not remove the barrier, but at least it won't add an extra one!
Celebrate your success.
In a game of balance, it's vital that you celebrate what you do well! Keep realistic goals and do a little something each day to help you towards them. Celebrate each step you take! Each little action will add a sense of control amongst the chaos that is our lives. Enjoy the positive relationships you are lucky to have and use the support network you have around you.
As part of a healthy mind, know that ups come with downs. In fact, it's the downs that make you appreciate the ups! Without them, would we even feel joy in the first place? Use challenges as an opportunity to achieve yet another thing! Don't seek drama because this life is stressful enough as it is. Aim to learn the difference between a destructive reaction and a mindful response; they often have entirely opposite outcomes.
Many emotions are perfectly natural responses, but it's only through open lines of communication that we are going to learn about which emotions come to us all, and hopefully generate a general consensus about 'how much is too much?', enabling us to identify when we need more targeted support using the growing range of resources available. Good luck, friends: you've got this!
