Mental health is always a very personal thing .today on their anniversary I remember someone close in my family who struggled but was much loved .
Everyone has their own thoughts and doubts about things,I find it key to try and compartmentalise things. I've learned as an exercise that helps me ,get a sheet of paper and draw a line down the middle ,list my worries and doubts on one side and more importantly list the good things in my life on the other side of the line.
Often the negative thoughts flood your mind and that's when you need to compartmentalise them and list out all the good things. What makes you happy ,your family, your friends ,an interaction you had with a stranger even where you shared a few passing words and a smile.
Life is a struggle at times but don't be alone in that struggle ,you are more loved than you you so always go to that positive side of the page and get help if you need it.
