Help, lexapro 10mg suicidal low moods

hi

i have been taking lexapro for 19 days now and just feel really rubbish. I asked my doctor to change from my previous meds (fluoexitine), but lexapro has caused me severe increased suicidal thoughts and really low moods and heavy depression. i really want to stop taking them and can’t get through to my doctors to get them changed, just looking for any advice on what i should do. Other medication hasn’t made me feel this bad apart from sertraline i tried years ago.

samantha how are you today ?
