Sam that is really great that you are thinking about studying. What a great thing to do to get your mind on to something else and how useful that would be.
I worry a lot too, i use the serenity prayer from GA a lot. God grant me the serenity to accept the things i cannot change, courage to change the things i can and the wisdom to know the difference. Sometimes i say this over and over and i really think about what is in my control and what isn’t. If it is something i cannot control then i have to try to let it go and let be what will happen. if it is something i can control then i try to look at what small steps i can take to help toward the situation or make it a bit better. it is hard to let go some days but i just find that this helps. keep going sam on this journey, you are not alone here.
