Get that off me!

Hi,
I am a new member. Returned back (4 yrs ago) to Chennai after 8 years in Singapore.
I played Veena and was selected Grade B high artist for All India Radio before I left.
I had performed in small gatherings in Sabhas here and was one time the best young talent featured in dinamani kadir. Since my return i have not.

Approaching this site to lose weight. 5' 4" weighing 99Kgs, I have lost quite a bit of my briskness and would love to regain it soon. I do all housework. No exercise or diet.
Nowadays, I find my mental energy is not where it used to be and all my activities are punctuated with blank staring rest
I dont read much and never watch TV.

Worse, I think my food habits were the same as before when I was around 80Kgs.

I dont snack. My food is pure vegetarian and I love coffee.

My mental state is bad for 2-3 minutes a day as I fall to depression mode where I am not in control of what I shout or throw.

My Veena practice is not regular but I still enjoy it.
