Is this mania? What do I do

I had a week long drug bender which is so out of character for me. Really hypersexual and reached out to past hookups, haven't taken my diabetic pills for almost a week and practically neglected my pet (she's fine now after I calmed down a bit.) Also when I say drugs I mean HARD ones, I only do weed and never done any of the other ones I did last week. I'm also not sleeping/sleeping too much, doing pills and other things I kinda snapped out of it after friends told me it was so out of character for me. Now I feel super active, drinking at 12pm and I'm super panicked about my state of mind. I'm alone in my room right now but I don't know how much more I can take I've convinced myself I'm doing this out of attention but maybe I'm really wired wrong I have a Dr appt tomorrow to talk about it but right now I feel so weird like I know my brain is overloaded and I want to do more drugs. Like a lot more. What is this? Btw I've had mania before, I think, that lasted a week and ended in the hospital with a panic attack, but only been diagnosed with generalised depression and anxiety
