Weight gain on anti depressants

Hey guys, I’ve been on Sertraline 50mg for 8 months and i have put on 12kg.. Weight has always been a huge issue for me especially after losing 50kg and feeling happy just to take anti depressants to then start gaining weight all over again. Can anyone recommend any anti depressants that will either cause weight loss or not affect it at all. I suffer from depression and anxiety and i also have BPD. Thank you guys 🩷
