tell
mom dad brothers sisters ......like hooligan said husband/wife needs to know
those ppl should know since they would be the ones contacted in times of distress or u get hit by a car .........plus having them in the loop helps make it easier when u are off track

the rest of them ........tell them what ever u like as for weight gain say getting old and winter months (if a bunch of weight seeing a doctor about it but not under control yet nothing bad some gland out of wack have to ask them the name get back to yah )

just rem the bigger the lie the more it takes to keep going .......deflect the ?s ....answer truthfully but leaving out factors do not want to share.....finally this is little tricky word play .........tell them with the correct set of wording that has 2 meanings one that is the truth one that they will jump on and think it is (doing this u are not doing anything horribly bad just not correcting a misleading thought )

u sleep like a baby knowing u did not break your morals or codes ..........someone might be smart and figure it out with time when they do lvl with them and ask to keep it to themself because the stigma / u do not want ppl treating u different
