Methotrexate and irritability

I have been on Methotrexate for about 1 year to treat RA. It has worked great for pain BUT I have noticed a lot of things going on that I've simply contributed to life. I have severe headaches, dizziness, extreme fatigue and major mood swings (depression and anxiety). I've seen some things posted on the internet about these being side effects. I am going to talk to my RA doctor and see if there is something we can do. I have been so bothered by these symptoms that I would just about prefer the pain to the constant feelings of irritability and depression. What are some other medications people are finding useful of RA with out the side effects????

I am 28 and have lupus, I was put on 10 mg of methotrexate last week weekly. Im expierencing some really weird side effects, atleast I think there side effects. My lower abdomen became very sensitive, I couldnt even touch the area where my uterus is, and now my breast have enlarged by a whole cup size and become very, VERY sore. Like the sore you get when you first get pregnant but I had a tubal ligation 6 years ago so pregnancy is out of the question. My heart beat is irregular and caffene seems to realy make it worse. I am soooo tired too, omg. I can't believe how tired I have become. And my hair is falling out, every time I shower it falls out in handfulls. Has anyone else experienced any of these symptoms? If so please share!
