Letting go is so hard. Try hypnosis. I know it might sound crazy, but find a certified hypnotherapist. It really can help move past things.

Hi, I can totally understand your pain. My advice would in tune with the above, mainly talk it through with a professional therapist but I would also recommend that you take each day as it comes and by that I mean experience every emotion and don’t try to run away from experiencing anything. I learnt that this is the trick – to truly experience everything as I too have recently went through something similar and I realised that the best thing you can do is to actually feel everything that you want to feel. Just let it all out and over time divert these energies elsewhere. Second piece of advice pertaining to your situation is to set boundaries – set boundaries with regard to what you will tolerate in future relationships. Please know that you must look ahead no matter how hard it is and how much further in the future you will want to pursue another relationship but start jotting down things somewhere (in a notebook maybe) about what you will do next time so as to prevent yourself from getting so hurt such as maintaining boundaries as I mentioned before. For many, a boundary is as simple as not sharing too many personal details so as to prevent the occurrence of an emotional attachment until and unless they truly believe the other person is worth getting a relationship into with. I hope this helps. Much of the advice in this rely is from personal experience. best wishes and Namaste.
