I am sorry to hear of the circumstances you are going through with your mother.
Unbeknown to many people in my circle of friends, i went through about 3-4 years of depression/anxiety attacks starting when i was 18.
It was pretty much the result of my father's passing away very suddenly and alot of things that had happened to our family leading up to his death.
I had always managed to keep a brave face on things to work colleagues and my social group but inside the moods were killing me.
I managed to pull through with a combination of going to the gym 3-4 times a week to boost my confidence and then started to see a hypnotherapist once a week for about 2 months.
It was only on the final session that i finally broke down in tears and released all the pent up emotions that i had been holding back for so long.
To this day, i know when the signs of depression could be coming back but by keeping myself active (walking/gym) or forcing myself to pick up the phone and interact with someone every day, i know i can combat going back to that dark place
My thoughts are with you Scooby and i hope that things improve in time
