I feel like I don't love my puppy, and I'm absolutely lost.

I've adopted a mix race puppy last year, she's been with me for 6 months. She's currently 8 months old and weighs 41lbs (yeah, she's huge). Her mother was a mix raced dog and her father was probably a german shepperd (the folks at the shelter didn't know for sure).

We've had a rough start because she was a very scared puppy, but it got better when she was around 6 months old. But my life is curretly a nightmare and I don't know what else to do. I feel like I do feel some love for her, but I've been having a hard time connecting with her and liking her. And I don't think for a second that this is her fault, I just don't think I'm enough to take care of her.

Walking with her is a nightmare. She's terrified of the street and constantly barks at other dogs. Often times she gets so anxious that as soon as we get home she throws up. I've been trying to do shorter walks, but it's only been a 2 days, so I'm sure I wont' see any results so soon.

She's desperate for attention and bites things she shouldn't when she doesn't get the attention she wants at the time she wants. She bit my girlfriend's cellphone (cracked the screen), my friend's PSP, the remote control, my own cellphone, the couch, the corners of my bed. I just feel like she's gotten worse the last month or so and I don't know what else to do. She has toys, and things appropriate for her to chew.

My friends were super supportive of me getting a puppy so I don't have the guts to tell them that I've been thinking about returning her or finding her a new home where her needs will be met. I've been speding so much money with the stuff she broke and the stuff she needs to be distracted and I'm at a loss.

I don't have enough money to pay for a trainer (I've spoken to 2 so far) and I've tried many things I've seen on videos online but it doesn't seem to work long term.

I feel stuck with her and I don't know what to do, because she deserves better but my mental health is at an all time low because of this whole situation.

I don't know what else to do.
