My life has had it's ups and downs. Suffered severe depression on and off since childhood. Spent time in a psychiatric hospital being treated for anxiety and depression. Been so low that sometimes I have done dumb things and been arrested. Turned to alcohol and other drugs at one stage, didn't help, although at the time I thought it did.
It's taken me many years to learn that although the "happy pills" help they aren't the answer by themselves.
As difficult as it maybe your own outlook on life dictates a lot to your mental health and well being.
If you are feeling very low Nailit seek help.
I couldn't have lasted this long with out support.
Ps: I don't wish for my life to end now, I used to, it's not always great but I enjoy the good times.
