Suggest Treatment For Bipolar Disorder And Depression

Question: I'm XXXXXXX, a 23 year old just trying to get some information. I dont know whats wrong with me. Or if there's anything wrong to begin with! I personally don't think there is something wrong with me, but the people close to me believe there is so here I am, I'll give it a shot.. I don't really remember when it all started but a few years back it seemed like it all just got worse. I started having these periods of time where I would get into this weird little phase where I just feel like crap for no reason. I just didn't want to do anything. There were days where I wouldnt get out of bed, I just sit there and feel miserable. I cant get myself to get up and go to work, its just so frustrating. Its like a funk I get into. It makes no sense to me because there is really nothing in my life to feel crappy about. And when I finally get out of it, I feel great! It's like it never happened. Im back to feeling well, ready to take on the world, ready to get things done. And i get things done! I go out have fun, do as I please and just have a blast. I never thought this was an issue until it started to cause me legal/money issues. But as soon as I get somewhere, I get back into my funk and I feel like I take so many steps back.. again..
It last a few weeks or so where I just feel shitty and all I want to do is sleep. I dont think it ever lasts more than a month but a month feels like forever. That's another thing I cant seem to get under control. My sleeping habits. Its like at times I have all these ideas and theyre all running through my mind that theres no time for sleep. I cant shut my brain off. Even when I know I have to be up early. So I end up doing things all night because I have all this energy and cant stop. I feel everything is moving too slow and i have to keep moving! But then there are times where it seems like I cant get enough sleep. Im exhausted and just want to stay in bed all day. Its really hard because there are days where I cant seem to stay fully awake at work, or I just don't feel like even trying to make it to work and pretend I feel okay. I feel like im always either having the time of my life, or spending my time just going on and on about how miserable I feel. During these times I worry too much and give myself anxiety just thinking about it and then im always irritated because I just want to be left alone. I finally agreed to see my primary doctor and was put on zoloft. Well i was taken off the zoloft about 3 weeks in and switched to seroquel and ativan after a hospital visit. I have since then been reffered to a psychiatrist but have been putting it off for one reason or the other. ( mostly because it can't afford it at the moment) so here I am. Asking for advise. So my question is if seeing a psychiatrist a good idea? Should I even waste my time??
