I’m so confused

I’ve been with my boyfriend or about 4 months now. It’s been great, he makes me feel amazing and is so supportive. However I always have this doubt in my head. Like do I love him or should I break up with him. I have been bed ridden for days not eating crying because idk why I’m getting these thoughts. I know I love him because if I didn’t I wouldn’t feel like this. Before him I had a partner that I ignored red flags and bad treatment so now I feel like I’m second guessing myself. Now when I see my current boyfriend I feel happy but also so much anxiety.

Does anyone have any advice on what to do and how to handle these thoughts. How do I know if they are real or just intrusive del sabotaging thoughts.

Ive been off my meds for a while so I know I’m currently very unbalanced. I’m getting reevaluated soon so hopefully they have more insight. But in the meantime I want to be able to cope.

Any advice is appreciated :)
