Ughh help please

Help ! 🥺 I feel like the worst mom dog right now. I currently work full time and I’m full time student. I never have time for my dog. I feel horrible I do feed him and I have my dad feed him and let him out of his kennel when I’m not home. Which he is outside for hours playing. My dad tries to play with him too but since he’s a big dog. My dad is older can’t do much. I give him attention but only for few minutes like 30 mins. My dads friend been wanting him since he saw him as a puppy. At the time I said no because I had no school going and my dog helped me out through my depression. I feel horrible tht he doesn’t see me as much as I want him to. I been thinking if rehoming to my dads friend since he’s always asking my dad how’s my dog. I feel horrible rehoming because I don’t want to think I don’t love because I adore my dog. I wouldn’t trade him for millions of dollar. I’m so stuck but overall I just feel horrible. Please help me don’t judge me nor mean comments. I already feel bad as it is. I just wanna know what would you guys do in my situation. I feel like rehoming him is the best but it’s just hard for me to let go

Edit: he’s not in his kennel all day. He comes out and exercise for an hour then he’s outside 8am until I get home he’s back in his kennel. He was in my house before but he just enjoys being outside. He was miserable inside my house. He hates going in. All night we would hear him howl and he would wake me up in the middle of the night to take him outside. He’s a husky mix with Doberman. Just some dogs can’t stand being indoor dogs. As what I learned from him.
