I had repressed most of my memories of the abuse that I suffered as a child. However, in the past when I was reminded of it I would use alcohol to numb myself to my feelings ...It worked for a while....until it didn't anymore! Then I started having total blackouts, waking up projectile vomiting, having 3-day hangovers, and getting into trouble with the law. I was so miserable that I would pray to die and I ended up in the psych ward of our local hospital several times for suicide watch.
I don't recommend alcohol as a way to cope with trauma. In my personal opinion, alcohol is a negativity magnet. It draws negative energy towards the person drinking it. A lot of homicides have included a person or persons who were drinking alcohol. If you need a way to relax and cannabis is legal where you live, I would recommend seeing a doctor and getting a Medical Cannabis Card. But even then I highly recommend you work with your doctor, so you do not increase any feelings of anxiety or paranoia. Cannabis can help some folks, but ya gotta be smart about it. It is not a cure-all for personal problems.
Having said that, it is probably best that you don't use any substances other than what your doctor prescribes.
This just represents my 2 cents. Please take it for what it is, ....just one man's opinion.
Wishing you the best,
