Disproportionate response to partner going away for a month
New to this subreddit but seems like a good place to ask for advice on how to get my out of my head for a particular situation. Quick background, I was with my ex for 9 years, then (what I felt was) quite randomly he broke up with me and left me, literally left the house and I never really saw him again. It was a harrowing experience. I didn’t have any family around as I was living in his country. I found out several months later from other people that he had been cheating on me for many years prior. Anyway, I worked through some of it with a therapist but I’ve since moved back home and all that change has made me begin processing it again. I also met someone and we are in a very loving relationship, but I am displaying some pretty frustrating and horrible symptoms of abandonment issues. During my depression and all the change, my partner has been so supportive and now he has gone away for four weeks, I feel bereft. Which is ridiculous because he is coming back and it’s not long at all, but I can barely communicate with him while he’s away. I feel like he’s fully left me, which is ridiculous but it’s just how my brain is reacting. I’ve probably become over reliant on his support and now I feel like I’ve been left in the lurch. How on earth do I act like a normal adult? I think it must be down to the depression I’m experiencing, but I am trying to keep busy, have increased my meds, and I am trying really hard to communicate (replying to texts, asking how his day is, telling him when I’m not feeling able to talk properly). But I know I’m disproportionately responding to him leaving and I don’t know how to stop doing it. Thanks for any advice/if anyone has been through the same.
