Struggling with PTSD Symptoms and Socializing

Hello I have two questions. My PTSD is the worst it’s been. Two strange things are happening now that it’s in full throttle mode: 1. I have flashbacks, not to the particular abuse situation but any memory that had some negativity attached to it. 2. I can’t seem to socialize or anything. Picking up the phone and texting back is so hard. The idea of having to hang out with somebody and know they will never understand what I’ve been through and try to act normal for a couple hours it super scary. Plus I’ve become very mistrusting. Any thoughts guys? I don’t have a therapy session until April so any information to give me some understanding of what is happening would be great.
