Patient discussion about Hardness tests.

Q. How come it’s so hard to loose weight? It’s easy to gain… Every time me or any one I know start’s a diet it always ends up gaining more weight than before…go down 6, than go up 7…is there a way to stay?

A. I think that the key to weight loss is not so much as dieting but taking control over what and how much you eat. I eat at least six times a day, thats four meals and two snacks. The protions that i eat however are not that big. I mostly just eat until I'm full or just satisfied. I really dont excercise either except for walking and I have lost 55 pounds over about a 3 or 4 month period. I LOVE food and the few diets that i did try didnt work, either because I was still hungry or I just didnt stick to them long enough to see results. I don't know if this works for everyone, but it worked for me. I think this worked because eating six meals a day kept my metabolism running almost constantly, so i ended up burning more calories than i took in. This may not take the weight off fast, but it can help you lose weight and keep it off. Hope this helps.

Q. I have a hard time to understand my Friend who is with bipolar disorder Hi, I am Tom here my Friend suffers from bipolar disorder and I have a hard time understanding how he thinks in his cold, emotionless phases?

A. It is very difficult during times of depression for friends and family to understand why their loved one seems to feel nothing. During these times the person suffering has nothing in them to give to others, they are consumed with dread and can see no light at the end of the tunnel. To them the world is cold and empty and your love does not shine through to them. It is really important to stay supportive and patient and try not to take these thoughts behaviors personally, they dont have anything to do with you.
Is your friend being treated for bipolar disorder? If he/she is being treated and still suffering with depression perhaps a change in meds is needed. Be present in your friends life no matter what the mood is for the day. Come by and say hi, bring your friend something to eat or just hang out and be an ear for your friend to talk to if he/she wants to talk. You cant imagine how important your consistancy in the friendship will mean, regardless of your friends mood.
