Crows feet Botox - still swelling after 5 months. What can I do?

I had Botox for the first time in my crows feet 5 months ago, swelling under my eyes/top of cheek bones occurred 2 weeks later and has still not gone! I’ve never been so depressed about my appearance in my life, I look about 20 years older and no one can help me, I’ve tried absolutely everything and nothing is helping
