Hey Pinkrose&Beth,
Pinkrose, i'm no stranger to feeling depressed so i'm no person to be trying to help you with what you should do...but this is my experience and what has helped me..
Counselling once a week, cos whether we know it or not sometimes there are little things niggling away at us that we don't even realise.. for me it was some painful stuff from my childhood that i 'd burried so deep i didn't even remember them until my counsellor dug them out of me. (don't ask me how, but i presume all her years in college had something to do with it!

)
Anti Depressants, now i'm not saying your as bad a case as i am/was, but a visit to the doctor and a chat about how i was feeling, really helped, sometimes just chatting to another understanding, professional human being is all it takes for the emotions to come flooding out...i'm not a fan of taking anti-depressants but i have to admit they did help me during a really rough time a year or so ago. Your doctor will point you in the right direction..
Exercise, again anyone how knows me knows i'm a big slob who wouldn't walk to the kitchen to make myself food if i was hungry (during the rough days) BUT i must admit when i get off my ass to go for a walk or a swim or whatever, i might be slow to get up and go, but deep down i now know that i will be feeling 100% better afterwards..its not an easy one , especially with the horrible irish weather, but IT DOES work to knock the depression on its head!
Food, again anyone who knows me well will know i'm very partial to chocolate, sweets, fizzy drinks, take away food (laziness..hate cooking) and all things bad for my body. Now i'm not saying i've turned into an earth mother sort who only eats organic unprocessed foods.. BUT i try and eat some fruit everyday, i TRY (and don't always succeed) at keeping the sweets & crap out, and i try and cook a meal every evenig instead of resorting to the nearest take out..
Looking after myself and doing things i like doing... I was exhausting myself trying to be good to everyone else (so i'd be accepted

) and not really looking at and thinking about the things i enjoy doing, so i've started to go to the cinema an odd time to see a movie i want to see (yes on my own!!!

) and generally taking better care of myself and my beauty regime(which makes me feel better..when i look better)
Now i know i'm rambelling, and this is MY experience and what has helped me feel better, i'm not tryig to advise you or tell you what to do, or even suggesting you do any of this..this is my story and i feel much better, but girl you need to find what will make you feel better and happier.
I'm not out of the woods yet..i'm just starting on this journey of self care, and i've to be very careful to keep it up or i could be back to taking 2/3 prozaic a day..which i do not want to do... and as much as right now you might be feeling like there is no light at the end of the tunnell or that there is nothing you can do to help your situation, always remember 'there are different ways to skin a cat'..crude but true.. there is always an alternative to the route you find yourself going on, and any problem has more then just the one obvious way at solving it.
I know i'm rambelling, but i hope from you hearing my story you can feel better and see that there is light at the end of the tunnell... take care of yourself girl!xxx
