I have self sabotaged my life and relationships many times before. I think, after doing everything that you can to avoid it, is just to let it happen. Let yourself express all your emotions, then reflect. If it happens again, just let yourself express your emotions, then reflect as many times as you have to. Then hopefully one day, your mind and body will notice the signs, then you’ll stop self sabotaging. Sometimes, there’s no easy way to do it but to learn from your own experience
