Some of the self esteem courses are worth doing.I've been told it's fine to more then one as most don't use the skills we learn anyway takes awhile for them to sink in....

I honestly don't think there is a way to boost "self esteem" in a down moment. I think it takes consistency on a daily basis. Wake up every morning and first thing say or write something positive about yourself. Eventually throughout the days you will find the positive thoughts will replace the negative voices in your head.
I do however think you can make yourself feel a little happier in a down moment by taking a deep breath and visualizing a happy moment or joke you heard. I do this sometimes by accident and I have found the rest of my day is much smoother. I usually visualize moments from movies that made me laugh out loud, and sometimes I end up lauging out loud again while it plays in my head. (try to use this technique when you're alone or you might look a little nuts)

Things that can give a boost are exercise. It always makes me feel good to donate to some for of charity and reminding yourself of what all you have survived and accomplished no matter how small u think it is

Work helps a lot to

I start something and finish it, however long it takes small or big doesn't matter. It helps me to know that finishing things will let me feel I've accomplished something. It's not a small matter to feel that way.

In the down times I take myself too seriously.
When I'm doing better I remember my wonderful sense of humor and my many adorable faults. I fancy myself a southern relative of Woody Allen. LOL Anyway my sense of humor helps me to boost my self esteem. If I can laugh at myself then I'm a pretty good guy. I know the logic is shaky but trust me ,for me it works.:p

For me it is looking in there mirror for all of the good things I see, And then looking deeper for all the good things there. It doesn't even have to be a big thing, you might like the shape of your nose or you might like how neat and tidy you are or you might like how devoted you are to other etc etc. Just find even one small thing you like and hold onto that and the small voice in the back of your head that tells you that all those mean things you think about yourself aren't completely true. Big Hugs and lots of love!!

Apologies for the slow reaction time in getting back to everyone; I've been busy today. But these are good points from all of you.

Going to hop around with hugs for those of you whose profiles aren't private, if yours is private, I'll place a hug here for you:
