I have been on every birth control imaginable since I was 12 year...

I have been on every birth control imaginable since I was 12 years old (extremely heavy periods/ hospitalized 3 times for cramps...excellent way to view womanhood!) Every single birth control I've been on I've had side effects such as: severe mood swings (crying over nothing, starting arguments for little things, weight gain/loss (which I don’t mind), headaches, nausea, anxiety....etc. After telling my OBGYN about my symptoms I was having while on Seasonal, she tried to diagnose me with bipolar disorder...long story. One of the worst symptoms I've ever had out of all of these was the loss of sex drive. I did not become sexually active until I was 18 (I'm 20 now), my boyfriend of a year now constantly reminds me of my lack of sex drive. I was on the ring (been on it for a year) when we first started dating, I slowly started losing my sex drive (nothing serious, more foreplay) and I started having weird mood swings. We fought a little not really noticing my fun outgoing spirit slowly decreasing. I spoke to my doctor who suggested yaz…bad idea. I gained so much weight and I started getting acne! So I switched to loestrin which I started taking in November last year. At first I liked it, I didn’t have a period until last month, which only lasted a day (no blood just the brown discharge). I don’t mind not having a period, while I was on the seasonal I didn’t have a period which is fine. I do mind the severe mood swings I have acquired; I’ll have a good day but if one thing happens that in the least bit upsets me I’ll go into full aggression…which isn’t good because I work with people on a daily basis. I had a full week of depression. I did not want to converse with anybody I just stayed in my room after getting off work and cried. I started getting acne on my face and my back. I’ve gained almost 15 pounds (I’m 5’4”; I’m not too thrilled about being short and chunky). The worst is my relationship is on the rocks. My boyfriend tries to understand what’s going on, but it’s hard for him. I used to be incredibly “active” with him, now if we ever have sex and I get distracted by a dust particle I lose all interest and dry up. I tried talking to my OBGYN but she insisted it wasn’t birth control. I asked her if the IUD would be a good option, but she won’t give it to me because I haven’t had kids yet… so at this point I’m thinking about changing doctors and stop taking birth control all together… I’d rather not take anything and use other methods of birth control than suffer like I have been.
