I'm so sorry you had to go through this.
I had a similar situation earlier this year which resulted in surgery to remove right my tube and the ectopic. I can relate to that feeling of not knowing what to feel at the moment. You've been through a lot physically and emotionally. Take it easy during this time, take it day by day, there is no need to rush your recovery.
I can share some of my experiences but each person might be different.
For me I was in pain after the surgery and paracetamol didn't even touch it. The nurses had given me codeine but I think that was making it worse as it it can make you constipated. I felt like I was so full of air and painfully bloated, it was just so uncomfortable (they do actually fill your stomach with air during surgery). The nurses ended up giving some medication for the bloating too.
The pain does get better after a few days but I'd say it was probably a week or two before I could stand up and walk properly again without looking like an elderly lady and feeling like my insides were going to fall out. And probably a month before I felt physically more back to myself overall.
The emotional side was a bit of a rollercoaster, I'm not sure it's something you ever 100% recover from emotionally but it does get easier with time. One of the worst parts was leaving the hospital, meeting my OH who was waiting with new dads picking up their partners and babies. I remember wanting to cry so much at that point - for him aswell - i remember starting to cry but it being too physically painful around my stomach so I had to just hold it in.
I felt a huge mix of emotions, relief, sadness, grief, anger at the hospital for poor treatment & delayed diagnosis, some resentment of other pregnant people that weren't going through this. Some days I was grateful, particularly for the support I had around me. Some days I just felt nothing, a bit numb.
The best advice I could give is to talk. Talk to your partner, to people close to you that you trust and talk to the many people on here that have had similar experiences and can support you through this.
Also, go easy on yourself, take this time to rest and do what you need to do to look after yourself. For me it was binging on crap reality tv with a nana blanket on my knees and knitting.
