Serious Advice Needed!!

I'll start here...so in November my daddy got sick..really sick and no one knew what was wrong..we all lived together...me, my husband, our three children and my dad. I took care of my daddy and of course everyone else. By Now it's December...keep in mind we haven't had any kind of relations...mainly by I've been so tired plus working and taking care of my daddy...now someone who has never taken care of another person probably won't understand where I'm coming from but o well...so by now we have found out that the only man I've ever loved truly and whole heartedly is now dying of stage 4 cancer! Who never even showed a symptom up until now! So watching the days go by with my daddy getting worse and worse and further away from me and further...I stay day and night at the hospital with him! No help from anyone else or either of his other two daughters. I'm only 26 and my precious daddy was only 61. So this is very hard to deal with and too cope...so now we are in March and we still haven't had relations and my daddy has been deceased for only two weeks now and I'm not ready...for one I'm too depressed and I feel like he's pushing and rushing me to "be ready".. am I overreacting by asking him to be patient or am I pushing him away? I feel like I can't and don't want to get out of bed but am being forced to. My daddy was my everything! The only parent I ever had...I'm just hurting so bad and need some direction....I've also been on BC pills for over a year and have heard that that too makes you not want to have sex? Help!?
