Hi.

From what I see you already know that you are not bisexual. If you were one, then you would be capable to feel with a girl what you feel with a man and that doesn’t happen. You were just curious and you indirectly had the permission of your mother who also experienced with a girl. You had some dreams with a girl and this caused you worry and anxiety, and then your brain tried to make sense to your anxiety so you remembered those experiences from the past and you took it as a sign that you may be bisexual.

You are also aware that because of your fear of getting hurt or of the relationship with that man not working out, you kind of made yourself unconsciously feel uncertainty about your sexuality, so you can avoid getting hurt and being left.

When you have those thoughts about whether or not you are bisexual, accept those thoughts and don’t panic automatically. If you change your thoughts from “What if I am bisexual??” (worry) to “So what if I am bisexual?” it will help. If you ask yourself the second question your mind will automatically try to prove you that you are NOT… and then the next thought will be something like “I am not a bisexual.” You already know that. If you have some thoughts that doesn’t mean they are true, that doesn’t mean you have to believe them. You pay too much attention to your thoughts. As long as your thoughts only make you feel bad/anxious/worried for no reason and without nothing you can do about that practically, it means they are not useful and that you can stop paying that much attention to them.
