How do I get my sex drive back I'm only 23?

[torie]

I have been on birth control for about 9 years now. I started it because I had very irregular and extremely heavy bleeding so it's not really an option for me not to take it. I really can't go through the bleeding for weeks and severe cramps. But for some reason lately I have been having problems getting in the mood (about the last year). I thought something was up so I went and did some test and found out that I have hypothyroidism. I started medication for that and it has now been about 3 months but I still have no sex drive and even worse it's like a desert down there if you know what I mean. Is it just cause I can't get in the mood? Should I give the thyroid meds more time to work or could it just be from being on birth control for so long? I love my boyfriend so much...I don't want him to think that it's him plus I want to feel the passion again too. Are there any pills or creams that I can use to help get me in the mood? Or do you think that it could be another underlying condition?
