Help!!! Sorry it's a little long

So I suffer from borderline personally disorder and I had a mental breakdown in may I hit my boyfriend and tried to overdoses on pills anyway I have gotten the help I need to get since then and I am doing better but our relationship is very rocky because his family said they don't want me around at all and he has to go 5o everything without me as I am not allowed ot welcome anymore. Then all his aily does is bad mouth me and he tried to fix the issues but on one WilI talk to him about it.. do you think I should give up and leave or what should we do I'm so frustrated and they told him they never liked me all of it was a lie they only said it to try and support him..
