I'm making the assumption that the 90% is your bounce rate for traffic from Facebook and Google Advertising.
I'm also assuming that you probably have left all channels (mobile, tablet, desktop, various display channels, etc) on, and not using remarketing/retargeting.
If all that is true, then what you're seeing is normal. Heck it can even be higher than that in a lot of cases. Ideally, you need to be working on reducing that useless traffic over time.
But this easier said than done especially if you have a a small budget that will be completely gone within a few weeks.
PPC is such a hard thing to do because you need consistent funds for at least 1-4 months to truly test what works and what doesn't. If you don't have that, then there is no point in doing it.
My word of advice is either stop doing PPC and focus on less costly things, or if you're going to do it, then start by using only one ad network (doesn't matter; just pick one) and working within a single channel of that network.
Once you feel comfortable within that one channel, then start adding another channel and another channel over time within that ad network.
