I give up

Is it safe to say that this isn’t working for me if I’ve been on it for 7 months and I’m still getting cystic acne? I hate feeling this negative about myself, I just don’t know what to do with myself anymore. This is causing so much agony and suffering that I can’t even imagine what it would be like to have clear skin. I struggle so much everyday and hate my appearance more than anything. I wanted this medication to work so badly but I’m afraid it’s just not it for me. I’m on 150mg too which seems like a fairly high dose. I’m not sure what to do at this point
