There is a way to get over this. I first started figuring out how my past affected me when I was 14, and I pretty much figured out how all of my past events affected me several months ago. When I first started realizing everything, I blamed that person or people or situation for my habits and mindset. But I was smart though. I still also realized that because I now know how it affected me, I can no longer blame it. And so I started making forward progress because I built up the strength to swallow my ego and learned to blame myself for everything related to forthcoming issues in that area of my life. Just a few months ago after I got into a huge fight with my mother, I finally forced out into my consciousness the last bits of why I will always look at my mother as someone who still has evil in them, and I figured out why. With that, I determined a solution so that I no longer will fight with her or let her and what she has done to me and my family affect me. I had already done that with my dad a little over a year ago so my mother was the last step.
Psychoanalysis is very important, that is why I stressed to you so much about intuition. Be your own therapist. I have a voice in me that constantly asks questions like "why do I hate this person so much" and "why am I feeling this sensation of attraction towards this girl right now". Be your own therapist that you can use free association with. It is good because you especially know what questions to ask yourself since you know what you are feeling at that specific moment. And you can dig back as to why you feel that way, which then will lead to another question that you can answer. This cycle will continue all the way back to the root cause. I figured out and mastered my past, and because I forced myself to have the strength to be able to change myself and blame myself over other people and situations, my past doesn't not affect me anymore. Well, had it not been for my past, I would not be who I am today lol so I guess it still has left its mark, but you get the point. Ahhh, Sigmund Freud would be proud of me.
Now not everything from your past affects you right now though. There are other categories of psychology. Psychoanalysis is definitely a big one though and should not be overlooked.
So in short, yes you can move on from your past. The way to do that is to use your intuition and not overlook your emotions, sensations, or gut instincts, rather embrace them instead. Once you figure out your past, you cannot longer blame it because you now KNOW how it affects you. And at that point, if you are able to change yourself out of old habits, you have freed yourself from your past.
It's a pretty cool thing to learn because you can eventually bring up anything from your subconscious into your conscious mind. And with this, you can detect nuance in someone's tone of voice much better and read their body language especially well. Not only that, but it stops you from being manipulated by others so easily because you can catch what they are doing much faster than you otherwise normally would.
An example of this would be like how chicks get all these guys around her to do whatever she wants while still being kinda b!tchy towards them. The reason why these guys follow her though even though she may not be that pretty is because she is manipulating her body language and tone of voice in such a way that is purely sexual, which the man's subconscious picks up so he feels attracted to her, but his conscious mind can't process why so he doesn't know why. YOU however do, and cannot be subjected to such manipulation because you can see right through that bs, even if the girl herself cannot.
Another benefit is that you can control the vibes you give off because you are now able to control your subconscious more. What I mean by this is that some girls can tell when a guy is truly interested in them and when they just want to get in their pants. The reason for this is that she can pick up on the vibe they give off through their facial expressions, the look in the guy's eyes, mannerisms, other body language stuff, etc. and as such she will sleep with the guy who is authentic instead, who truly is interested in her. The guy who truly is interested in her may even be faking it to an extent, but is able to control his subconscious enough (because he is able to bring it into consciousness at will) to where it will actually change his body language, thought process, and mindset. This last part is really hard to explain so forgive me if it doe not make much sense. But basically, it allows you to master yourself. The reason why women tend to have much better game than men is because they are more intuitive than men on a general basis. This is because they are more emotional. However, because they're more emotional, their intuition can become more distorted and biased towards how they feel rather than a logical reason explaining why. This is why when men do commit to 'manipulation' as Poon King called it, they will always beat even the best women.
