The symptoms you describe do seem to resemble the manifestations of separation anxiety, particularly the intense anxiety and somatic reactions caused by the sense of instability in an emotional relationship. Somatization is a process that converts psychological stress or conflict into physical symptoms, and anxiety disorders are a common mental health problem that can be managed and treated in a variety of ways.
While you have made some progress in gaining self-awareness and understanding, there may still be a gap between recognizing the problem and effectively addressing it. Here are a few suggestions for your consideration:
1. It might be helpful to seek a professional assessment.
You might consider seeking a professional assessment at a hospital psychiatric department. An experienced doctor could determine whether you have separation anxiety or another anxiety disorder based on your specific symptoms and circumstances, and provide treatment recommendations accordingly.
It is true that there are effective medications for anxiety disorders, but it is important to note that they need to be prescribed by a doctor.
2. Psychological counseling and therapy
Psychotherapy, especially cognitive behavioral therapy (CBT), has been shown to be very effective in treating anxiety disorders. Through counseling, you can learn to identify and change the thought patterns that cause anxiety, as well as learn healthier coping strategies.
You might also consider emotion-focused therapy (EFT) or attachment-based therapy, which could be helpful in dealing with anxiety related to intimate relationships.
3. Self-management strategies
It might be helpful to try relaxation techniques such as deep breathing, progressive muscle relaxation, or mindfulness meditation. These can help relieve the physical symptoms of anxiety.
It may be helpful to consider that maintaining regular exercise, a healthy diet, and adequate sleep could also be beneficial for managing anxiety.
4. Consider ways to improve communication.
It may be helpful to communicate openly with your partner and share your feelings and experiences. You might find that establishing a mode of communication that is mutually supportive and understanding could help to alleviate your anxiety.
It may be helpful to consider establishing a support system.
It might be helpful to share your feelings with trusted family members and friends and to establish a support system that can provide additional emotional support when you feel anxious.
It is important to remember that while self-exploration is valuable, there are times when external help and intervention can be beneficial in effectively managing and resolving these issues. Seeking help is an important first step in resolving problems.

I can relate to how distressing this must be for you. It sounds like you're experiencing intense anxiety that's manifesting physically. Maybe it would help to focus on grounding techniques when the palpitations and nausea start, like deep breathing or mindfulness exercises. Also, discussing your feelings openly with your boyfriend might bring some relief. Communication can sometimes ease these overwhelming sensations.
It does sound a lot like separation anxiety or possibly an anxiety disorder related to your relationship. Have you considered keeping a journal of your symptoms and triggers? Writing things down can provide insights into patterns and what exacerbates your anxiety. Sometimes just seeing it on paper can make it easier to address.
What you're describing seems beyond typical relationship worries. The physical symptoms are telling signs of severe stress. Perhaps trying a different approach to therapy could be beneficial. There are various therapeutic methods out there, such as CBT or EMDR, which have shown success in treating anxiety disorders. It might be worth giving one of these a try.
The fact that you recognize the irrationality of your fears is a strong point in addressing them. Medication can be helpful for managing symptoms but finding the root cause and working through it is key. Talking to a psychiatrist about possible treatment options, including medication, might offer you some strategies to cope better with your anxiety.
