Despite some predictions, many of the answers you have already received are as good as any Rov will give you.
I would just like to add a point that has not yet been mentioned.
Before Matan Toirah, no one kept mitzvos asseh in the format that we do today, but chazal still state that the Ovois, for example, kept the entire Toirah. Many resolve this apparent contradiction through a simple concept mentioned in the Zohar, that their mundane actions were accompanied by lofty meditations that encompassed those mitzvos asseh.
Matan Toirah changed that for the men. One reason is that their reception of Moishe Rabbeinu’s appearance in Mitzrayim was rather lukewarm, whereas the women were all positive. Yetzias Mitzrayim was on account of the attitude of the women. The women did not allow themselves to get involved with the eigel. In general therefore, women are in less need than men for specific rectifications sympolised by these mitzvos. Therefore women today have a similar avoidah to the Ovois (and Imahois). A woman can achieve the same if not more by thinking about spiritual ideas whilst doing mundane tasks than men can do through the rituals that you so desire to perform. Women may also perform many of them if they wish as well – the best of both worlds!
A very clever woman who had returned to Orthodox Judaism one remarked to me: No wonder male baalei teshuvah find life so hard. Look at an average weekday minyan. Women on the other hand can take as long as they wish over their prayers, and put their whole heart into it.
Of course the same can be said of every Jewish man, only she didn’t know it, because everyone pretends that he’s OK.
Believe me, you’ve got nothing to be envious of.
