Alright imma give you some tips since you are starting out and its great to get feedback so here I am. Ok so I think all you need is more emotion you sound monotone so when you are angry imagine your boyfriend got taken away by a lets say this nicely a slut. So now use that anger and put in you lines over exaggerate if you have too. because exaggeration is better than emotionless and plus exaggeration can create a funnier result and punchline than a regular line so don't be afraid to be overdramatic. you got good quality too so you got a chance to be successful.
