I'm sorry to hear that happened to you. I had a very similar experience when I was 16. I am 23 years old now and I still deal with flashbacks (delayed sense of touch like you had also written about, sometimes it can be painful too), anxiety, depression, depersonalization, and dread. It's been such as difficult road but as you mentioned, it does get better but I just wish it would go away entirely. I have found that lessening stress, having distractions, and maintaining a healthy/positive lifestyle limits the number of flashbacks for me but sometimes I cannot control it... I am wishing you all the best. Remember there are others, like myself, dealing with this too.
