Sex drive help!

Alright, I've got a big problem.

There's been a lot of new comings in my life as well as a ton of changes (Change in diet, change in BC, 120 pound weight loss, plans to move, change in jobs, etc) and I also have several health issues (diagnosis' of Chronic fatigue syndrome, chronic pain, and joint hyper mobility syndrome being the latest).

My problem is I'm only 19 and my sex drive has tanked. And even when I am horny and want to get it in I cannot get wet like I used to. I used to me a freakin faucet and now it's like the Mojave desert down there. With all the changes I can't pin point the cause and I'm planning on talking to my doctor and OBGYN at my next appointment(s) but was curious if anyone else has had this problem and if they've found something that's helped. Whether it be supplements or medications or whatever.

My boyfriend says he doesn't mind using lube but it honestly makes me feel old and dried up. That and I feel like he thinks I'm not attracted to him anymore.

Help!
