I've started to get really depressed about life

I've started to get really depressed with life.I'm afraid that I won't get into heaven for all the choices I've made and things I've done.I'm afraid of the afterlife.I love my mom and son tremendously and if something happens to them I don't know what I would do.I'm afraid of my mom aging bc I don't want her to die.I've been worried about this for so long.life is going by too fast.I don't know what to do.
