They won't take your baby away - do go and see your GP. And don't be afraid to shop around to find a GP who suits you and you feel comfortable with.
We moved when DD was 6 months old, leaving my friends with children about 30 min away. The way I dealt with it was by having something planned to do every day. We did something like music, baby signing, 2 baby/toddler groups and library story time. It might seem pointless taking such a little baby to things, but it is just about getting out and spending time with other adults. We are still in contact with a couple of families who were at one of those activities and DD will probably go to school with their children - so it has also had a long term benefit.
I also sent DD to nursery 2 mornings a week from 6 months until I went back to work to get some "me" time. If you can afford this then I recommend it, as it was great for me and also meant that DD settled into nursery really easily when I went back to work.
I missed work when I was on maternity leave. To the extent that if I had another, I don't think I would take the full leave again. Having a baby can be boring and isolating. Don't think you are alone in thinking this. Other people experience it too, but it isn't deemed socially acceptable to tell everyone. It isn't a rejection of your DD, it isn't specific to your baby, they are all pretty dull. If you aren't a baby person then what you love in a baby is more the potential of what they will become.
Don't make any rash decisions, but it could be an option to return to work sooner than you have planned.
