My friends

Send them an email probably that might help . Or do ur best to find their problem and try ur best to help . If u dont find any chance to know your friends' problem then probably it means that ur friends seek loneliness for some days and I suggest you dont speak anything to them for some days but do them let them know now and then(say weekly)through sms or email that u care for them and chose to avoid frequent conversation with them only because they showed indications of avoiding you. Then they will realize how mean they have been and probabaly will send u an apology . Then you can enquire their problem.

Hi tzmmmm, There will be many reasons for your friends getting upset. It is not possible for us to know or get full details for their upset. Take for instance, for job---your friend would have scored less marks, Family----may be he is not able to adjust with them. How do we know their problem to give suggestion unless they tell about it. You dont get upset because of that, because you will have your own problems to be solved. Concentrate on that and be happy and help your friends when they tell their problem, that too if you feel it is genuine. Best of Luck.

relax, everything will be OK, you needn't do anything just heart what they said. They may feel more comfortable after talking with you.

Well, I have the same problem.. Friends are always in the first place... But now I find I don't need do something when they are sad. I just need to stand by their side, listen to them and give them my shoulders. That's the best comfort for a friend.
