I find taking life one day at a time helps .
Life is served up to us in day sized chunks, that is what is manageable as a human. When i start trying to live beyond that projecting my worries and anxieties into the future or drawing on them from the past it can make getting through now difficult .
Try to back off from the worries and anxieties , look at what you can do today to make a positive change. For those things out of our control send a prayer out to god , a higher power or the space aliens who run the universe …
Feelings change all the time , they come and go , nothing is forever . Things will either stay the same or not , accept today as it is "warts and all" , contentment is making do with what there is .
Have a sleep on it. It's a new day tomorrow i'm sure things will be different .
Bestwishes, m
