Healing crystals?

So for awhile now ive been looking the idea about healing crystals and just showing myself love and positive vibes and sending out positive vibes and just balancing myself. Question is I’m not too sure how to do that. I was meditating for awhile to help with anxiety and the only last so long. I’m pregnant and have always struggled with anxiety and ocd. I’m looking for counselors at the moment but i want to know if anyone can give me any advice on how to heal myself holistically? I want my baby to be peaceful and lately i feel like I’ve been letting a lot of stress get to me and overwhelm me!
