Siblings

My oldest brother moved out when I was 6 and didn't come back into my life until I was 9, but by the time, my oldest sister was moving out and I blamed it all on myself since I wasn't up that morning to say goodbye to her as she went off to work. That still haunts me to this day. They both came back in my life 3 years ago, when I was 13, it was going perfect and I thought we could all be a family again then my next oldest sister decides to move out last year. Right before Christmas. They move out and go to live with their friends and don't keep in touch with me, except when they feel like popping up at my school to say hi, they won't come by the house to hang out or see the youngest ones, it really upsets me because they are my siblings. But I don't want to be around them because they have been involved with drugs and gotten arrested and I can't risk my future because I was with them while they were on something and get caught. I have no clue where the live as of right now. Only where one of them works. & I have none if their cell phone numbers. But I don't know if I should try to keep them in my life because I really miss them or not. & if you think I should. Idk how to get into contact with them. Help me

I thunk you should goo down to that one persons work and help them get of drugs and to come home or at least try and if they say no be persistant do it again and if you do manage to hwlp them ask if they now where they others are have the one you already help help yu with helping the ones you haven't helped yet hope the helps
