Kitten, No future in the past, you love your dad so go visit your dad when you go into the house put your arms round him or just hold his hand and tell him you love him, he may not know how to react, but you can bet your life he will be feeling it inside, never ever be afraid or put off telling somebody whoever it is that you love them, do it as soon as you can, the fact your sister has done well has nothing to with how you are as a person and for you to think the way you do tells me you are one lovely lady, it has probably gone on so long with your dad not showing affection he may be to embarrased to or not know how to, but he will deep inside be wanting it, good luck Kitten, go for it, take care,Ray xx
