Hi. My regards to u on recovering from swine flu. Obviously u will have tiredness in your body . But you have to take nutritional food to balance Ur body. Start eating fruits. May be if u want I will provide balanced diet. Hopefully Ur doctor should have given you. So you will gradually gain Ur appetite. Dont feel low and irritated. As time goes u will develop urself.if u feel like crying do cry off totally. If u really can't come out of sadness you have to meet a counsellor or psychologist where they remove Ur sorrows and Ur worries. You have developed anxiety and frustration which makes u angry. you really need to calm down and avoid Ur tensions. Believe strongly that you can do everything by urself.
