I was watching a video clip on different ways to temporarily relieve depression. I can’t find it now, bu there are some very helpful pointers which I found. The presenter is a Dr. Rabin, and he suggests a website: healthylifestyle.upmc.com
One trick that always helps somewhat in calming emotions whether anger, frustration or depression, is taking in a breath of air, one to two seconds, and (if possible) going on a short walk can help too.
Try to keep in mind some humorous and cute stories or comments that you’ve heard or seen at some point, and when you feel yourself feeling “down,” think about them.
I hoped I’ve helped in some manner. Being that i am only a 16 year old, I’d feel to shy to say anything if this was in public.
I wish you hatzlacha, and as a cohen, i give you a brachah that Hashem should give you the koach you need to get through this situation as soon as possible!
