Aw Saradev! I am so very sorry you are suffering so much.
Please don't lose hope. You can beat this.
I was suffering too - I was in a lot of pain, I was stuck at home, I lost a lot of weight, and I also thought that I would rather die than continue like that.
I had an LIS done in May and my fissure is now healed. I admit, I had to struggle for a while, but I now have my life back and I'm very happy! I'm not in pain anymore I go out with friends, I'm starting to eat more tasty food (I even had a beer last week!), and I'm gaining weight and looking much better. I laugh, joke and I even dance (when I'm alone at home because I don't dance very well!) There is hope!
If I'm not mistaken, you had laser surgery and not an LIS? I'm wondering if maybe you should get a second opinion from a different surgeon. The LIS is considered the gold standard for fissures. Maybe you can talk to a different doctor and hear what they have to say. Meanwhile, are you taking lots of hot/warm baths? They can really help with the pain, and they also stimulate blood flow to the butt, which helps with the healing.
Please don't despair. Many of us had to fight like hell to heal, but we did it. Summon all your strength and find a doctor who will help you. You deserve to heal and have a good life, so you fight, girl friend! We are here to offer moral support. You can beat this!
