Pregnant and suicidal

Hear me out. Please don’t judge. I’m not selfish. I want my baby more than anything. I’m 15 weeks pregnant and was ecstatic when I discovered I was. I have a partner. We don’t live together. It took him a while to come round to us having a baby but I thought he was getting there. He has a good job. Earns enough money. I have a not so good job and struggle every Month even without a baby. He gambles and can be very selfish and horrible to me when he’s had a losing streak. I’m anxious in nature and have struggled with anxiety all my life. It’s worse now due to covid and the stress of not knowing how I will take care of my baby when I’m so anxious and a nervous wreck all the time. I don’t know how long I can cope with this feeling. I love my partner but he gives me no support whatsoever and I know that’s wrong. I just feel like I have no other way out and genuinely feel like everyone would be better off without me. I’m a failure and a nuisance to everyone all the time. I try to tell people how I feel but no one actually cares or understands. I guess I just needed to vent. How can I stop feeling like this and build the strength to carry on.
