depo shot making me crazy

I had the copper iud paragaurd and it dislodged my gyno didn't have another on hand so she suggested I get the depo shot so they had time to order 1 in. since receiving this shot my emotions have been severely all over the place. I have always been a very relaxed happy person so I don't even feel like myself. one minute I'm happy then the smallest thing makes me extremely angry then I'm crying. I'm in a great relationship for 3 ylears but I'm worried my sever mood is having a negative impact on it my personality is drastically different even when I'm trying my best to stay calm it is also causing me terrible anxiety. is there anything I can do to help get through the next two months I'm dreading having to feel this way. depo was the worst choice of my life.
