I feel lost someone help!

This is my first post here. I have been diagnosed with severe depression and anxiety but well both seem true I think I might have borderline personality disorder. I always feel like my friends don't actually like me, and that my parents don't understand my stuggless or refuse to acknowledge that I have any problems in the first place. I cant seem to make any new friends because I'm too afraid that they wont like me or that they'll make fun of me. I also get extremely attached to people that dont like me or people that I dont even talk to. I've been seeing a professional for about 6 months now but haven't made to many improvements. I still struggle daily with thoughts of suicide, low self esteem and uncontrollable mood swings. I've tried everything from meds to weed but I still want to die. If anyone has any advice please help.
