I wonder with your boyfriend if you aren't expecting too much. It sounds like you are a bit like me. No one is right because he or she doesn't meet every one of my needs. But your significant other is a person too with many needs of his own. I know I can't meet every one of another person's needs. That would be insanely exhausting.

While couple's counseling might be helpful, I would recommend trying to see things from his perspective. No matter how hard he tries, he will never truly understand your illness or your pain. He can't completely share it. He may may be worried about you constantly. He may even wish he could take your illness on.

Also, something I found helpful is having a diverse group of friends and family. Each person meets a need in me, but no one person is responsible for being everything to me.
For instance, my best friend has mental illness too (we met in an informal support group). I go to him to have conversations with someone who totally understands the way I speak and what I mean. I have a religious person who meets my need for deep talks about the spiritual. I have a therapist to help me work on me. Etc.

I know it's tough to find people when you don't feel well. However it's highly worth making the effort. I try for diversity in experiences, ages, interests, and backgrounds. I try and not overwhelm any one person with all my needs and expectations.

Well, my thoughts and experiences

Keep struggling the good struggle. Never give up.
