Help!!! Kitten suddenly afraid of bed.

So tonight my kitten 15wks was cuddling on my bed with no issues she later left and curled up in the bathroom on her bed blanket because that's where she usually sleeps just over the last 7 days we have been trialing her in our bedroom and she hasn't had any problem until tonight. After she came back from the bathroom she curled up again on the bed as I was pouring a drink she was very interested in what I was doing and got up on the bottom bed head she slipped off and my bf tried to catch her but couldn't now that happens regularly as she lacks any kind of co ordination but when he picked her up and put her back on the bed she went nuts attacked him and jumped off. I tried picking her up and I put her on the bed but she kept backing away from him and as I picked her up to move her to the other side she went nuts again and started to really panic and I ended up with 15 scratches because of this fit. I've put her back into the bathroom and she is fine with both of us cuddling her and petting her and she's comfortable in there now. But I'm concerned as to what caused her sudden fear and panic when she spends half the day and most the night on our bed - she falls off it quite regularly as well and she's never behaved like this I'm a little concerned.
Any help is welcomed as my other cats have never behaved like this either.

I would keep an eye on her and see if she remains scared. It may just be something about this last fall that's startled her - honestly, it may be the fact that both you and your bf were there and reacted. Most cats bounce back from this sort of fright fairly quick, but if she's still acting a bit off after a day or so, maybe pop over to the vet to make sure she didn't pull anything in the fall.

Truthfully, within a few days its likely she'll have forgotten all about it and be back to normal.

Thanks for your advise although now she has just had another two of those fear attacks. I picked her up like I always do and she completely freaked out like last night. She on the couch after that and my bf was petting her and she then had another freak out 10 mins after this other one. I have no idea where this fear is coming from we changed her diet maybe a week and a half ago to tuna and dry food as the vet at the pound said it was the best thing for cats I'm wondering whether maybe tuna isn't all the good for cats. Or whether worms may cause this. She's been dewormed but since she is a pound kitten the vet said it may take a while to get rid of them. I dunno I'm really concerned and I'm considering a vet appointment.
I've had a good feel around her body and applied pressure and she hasn't flinched and meowed or tried to get away from that so I don't think she's injured and I can't think of any new stresses in her life except for washing her blanket. I'm at a loss.
