Overcoming another feeling

Last time I posted here I had that problem with a feeling of disconnection....thankfully that subsided over a few weeks...much longer than I hoped it would...i still get bouts of it from time to time but thats typical, although I still liked hearing other peoples opinions on the matter

Anyways. I'm here again because lately another feeling/emotion has started weighing heavily on my mind.....and this one is really dominating me quite a bit, to a point where I just feel purely sad (in both sense of the word) about it, and this feeling is nothing less than menacing Jealousy.

To be honest, I would say that I am not the jealous type...unless say i am in a relationship and looking to keep things that way, but even so I would not be restrictively jealous, I would merely just state that such and such made me feel a bit weary....just so you know incase i get a bit grumpy later lol

But heres the deal. A house mate has recently aquired a new girl of the month....but this seems to be like the first one hes kept around for more than a few visits...now in essense this wouldnt bother me, it's his "style" to "womanise" as i see it and if hes good at it good for him....but this time, the girl seems nice, almost too nice, and it baffles me how it can happen. Shes friendly, sociable and all this and that, and its not necessarily that i like her...its just the concept of it that digs into my mind. Knowing that they be upstairs...getting it on or what not makes me turn green with envy.

What Im feeling when I look at her is a torn decision between wanting just to be my typical nice self and talk back or to be a complete and utter spiteful ****, somewhat unjustified I know but this is why Im here, thankfully ive been able to balance it out, a bit of spite has bled into a few lines of conversation but I'm good at holding my tongue. Despite that though its the thoughts of spite and envy that Im still left to tackle as they cook around in my mind.

Also, this seems to just have sparked a bigger problem because outside that , everywhere I seem to look now all I see are couples here and couples there. (yeah this is slightly still lonliness based I know) and all i can think about is how damn envious I am, setting up a vicious cycle where I get saddened by it and therefore more envious and etc. Its by contrast I don't even have any female friends. well i have 3 girls i talk to now on a regular basis but not one of them is even in the same country, which satisfies very few of my wishes ¬_¬ but anyways

If anyone knows what I'm talking about, or knows how I could possibly shift my mental attitude off this way of thinking, Id really like to hear it because unlike disconnection that can fade, I know that jealousy can end up eating away at you. Im already feeling pretty deflated by it. anyways thanks.
