Please tell me her behaviour is normal :(

Hi all,
I have a beautiful little 5 month old girl, she's my world but I'm sorry to say she is just so miserable! I don't know if there is something wrong or am I doing something wrong?
When she's in a good mood she's amazing happy and giggly... Everything I dream of but then she turns into a devil. Honestly she seems to be happy for about 1hour a day.. She doesn't really entertain her self alone so if I leave the room whilst she's playing she will stop and cry.. If I pick her up she will try to push away from Me.
It's really beginning to upset me as I feel like I can't take her out to friends or family as she will cry family days out are a no go and time in the house is beginning to become painful.
I may sound like I'm being dramatic as she's a baby but I'm a first time mum and I can't help but feel I'm doing wrong.
I would like to add she is teething, normally sleeping through the night but this has stopped as the behaviour worsens! Any tips advice or reassurance will be amazing
Thanks all x

Teething is enough to make anyone miserable! If she's in pain with them, that most likely is what is affecting her sleep too. As for the wanting you then pushing you away, they can be incredibly fickle little people. I'm sure it's a phase, don't think your doing anything wrong.
Do friends and family really mind if she's a bit whiny? I'm sure they'll understand Have you tried some baby groups? Ideally some which also has toddlers: they are always less moany at these things, and failing that at least one toddler is bound to have a meltdown and make your DD seem saintly in comparison!
