Rosy is wright,It is a good idea to stick with your friends who has positive thought about you, you will always heare their incouragement and they will tell you somtimes that you look great even in times when you look tiered and sik only to raise your self esteem and to incourage you. like that you will get used to have your own positive thought about your self also. Get away from negative people who like to critisize. Although my self esteem now is much better than the time when I was leaving with my x because he is a bully and abusive but it still afect me when people say I look very tired but I know now that these are not the people who I must spend a considerable time with.
Another idea is very helpfull to raise your mood is to look after your self well and to take it easy as much as you can. It worked witkh me although I am going through a realy dificult time now.
