Anxiety Medication

Does anyone take lexapro? I have the worst anxiety and depression and I’m going to therapy and my therapist asked my thoughts on trying medication. I’m open to trying it. I think I’ll be taking lexapro if I do decide to take it. I’m 15. And I think it may really help me. Anyway, did it do any thing like make you gain weight or did it not work for you? And if it did work how much has it changed your anxiety and depression? And how long did it take for it to change it? Thanks so much.
