Getting over the hump of using an egg donor :S

Hello ladies,  
Baby dust to everyone.  
I am a 35 year old female that was in a tragic motorcycle accident about 4.5 years ago.  I have primarily been focused on my recovery which has gone really well thankfully.  As a result of the accident I was diagnosed with a tranatic brain injury.  So, I am legally disabled.  
So my efforts to concieve were thrown off by the accident that shortly happened after I got married:S 
So my life has been a roller coaster the last 4.5 years.  Since I am overall doing well except for some impairments in speech & memory we have been trying to concieve for the last 1.5 years.  Nothing has happened :S I've used several ovulation kits and pregprep pills & still nothing so we saw a fertility doctor which recommended IVF.  So we opted to try IVF with no success :( we had 1 embryo service but it didn't get past the genetic testing.  So, we are back at square 1 :S 
We recently visited the doctor & she went over our options with us.  One being of getting an egg donor.  Which we hadn't thought of :S we only thought of surrogacy :S 
So, now I'm at a cross roads with my feelings :S we are going to move forward & do a shared fresh egg donor cycle so we can split the cost & not get hit so hard.  So, they would use my husbands sperm, the egg donors egg and I would carry the baby.  So, I'm trying to get over the hump of the baby not biologically being mine.  The baby would he mine because I would carry the baby & deal with the pregnancy only thing is that it would not biologically be mine. So, Im having a hard time accepting that :S I think I'm a nice looking lady and would LOVE to pass my genes one but not being able to is killing me :S I just know we do want a baby and they gave a 84% success rate with egg donor pregnancies so we are moving forward with this.  I just need help processing all my emotions :S please give your thoughts and feed back on this issue.  HELP:S Thanks :)
