I Am Confused About Many Things

I need to vent, so that I dont end up saying something to somebody that I most probably would end up regretting. And maybe putting my thoughts into words, would give me some clarity. Here is the list:

1) My career. I dont know where I am going, or what I am doing. I work a job that is a bloody dead end, I cant move out of it cz there is no similar job anywhere and starting out as a fresher is almost impossible. I cant go back to school, cz I cant leave my job. I know I should be grateful that I have one, blah blah blah, I have heard that, I have been trying to be grateful, but this is like a slow poison!

2) personal life. I have tendency to fall for all the wrong people. I trust too easily, give too easily. And am broken that easily. Latest fiasco, this guy, i dont understand, he talks on and off, when asked if you care, he keeps mum. he blocks me unblocks me on his own. sometimes nice mostly rude. I am trying to get over him, and he keeps pulling stunts and cripple me. and I dont understand why I am even bothered, except for the fact I dont seem to get over it! To cap it, family drama is bloody overflowing! I cant concentrate on that cz I am always thinking about useless people who have no value for me or my feelings.
