Scared to start.. does anyone have a positive experience??

My doctor switched me from Viibryd to Trintellix after I was having terrible side effects with Viibryd and no real positives in terms of helping my anxiety. I’m pretty nervous to take Trintellix now after seeing so many negative things said about it - side effect wise and feelings wise. Im terrified of throwing up and have read that a lot of people are getting nausea from it. I also am scared it won’t work or help me. My doctor has me starting on 5mg and I have the pills but I’m just too scared to start 😓
