Hi, guys. I would like to hear some opinion on what I should do in order to get rid of my weak-tight-omfg-he's-got-the-nuts-if-he-shoves-on-this-board pattern of thinking. I started playing texas holdem about 3 years ago but had no idea what this game really means untill 6 months ago, when a friend of mine, a pro player started coaching me. Imagine how much money I lost in the long run, believing that I was good, only because I used to have some good runs due to my native luck

Well, as I said he coached me for Hu games then I decided I should try low limits 6 max (I now play 50 NL). Thus, my husband started teaching me the basics. I changed a lot, at least my stats are completely different, from 40/15/2 I am now at the point where I play 16/14/4. I still have some issues though and I think that my problem comes with the post flop play. We all know it-s easy to play AA or KK most of the times...well my problem comes when, even though I'm in position and I raise with an AJ suited let's say, the flop doesn't really hit me. Like for example the flop comes AXX with two suited cards (none of my suit), I make my continuation bet and I get raised by my opponent. That's only an example of when I get scared. I usually fold on this kind of board, when my opponent is some good regular. I had a lot of bad runs due to my lately fear to 4 bet or shove.
Well I know I might not have been very specific, but the bottom line is what to do in order to change ? I think it's some psichological pattern that won't let me develop my game. Can anyone help me,please ?
