On keppra and I feel like I’m dying

I (23F) had my first seizure in 2023 and thought that was an isolated episode, so I never really took meds properly. Recently I got super stressed over something and had a seizure, after three years! Does this make me epileptic? I don’t know. Anyways I’ve been put on keppra and it’s just been so difficult. Losing interest in my relationship, rage, breathlessness, fatigue, depression? I feel like a burden to my boyfriend and my parents, but mainly to my boyfriend. I genuinely just want to end things with him just so that I can spare him the burden of having someone who can’t control their emotions as a gf. I get super depressed every evening and I start spiraling but I don’t want to vent to him because he’s always trying to make me feel better and I genuinely feel so bad and guilty. I also have zero friends and nobody knows about how bad things have got. I’m also unemployed so everything is just adding up. I feel like I should end things with my boyfriend before I hurt him coz how long can I keep trying to explain myself? I feel so selfish and like a horrible person. What do I do? Do these side effects get better?
