Help! My baby is in so much pain with teething and a bad cold, we're both going insane!!?

He's 11 months. He went from no teeth, to 7 coming in within 3 weeks. His canine are cutting now. He is a TOALLY differentt baby. Andd he has his first serious cold too. My poor little angel! I of course have tried everything under the sun after much research, and yes they help. Tylenol, orajel, teething toys, infant massages, walking him around, holding him and walking and bouncing when he screams. The problem is, I have become so despondent and stressed from no sleep, and working full time from home during all this. I hate to say this but I get frustrated with my son! Not with him, but his pain. Like when he arches his back, and just SCREAMS. It makes me want to cry, and rip out my hair. There are no breaks, not even at n ight. He went from sleeping 9 hours straight every night to 1 or 2 hours. I feel like I am having a breakdown. This is our first child. We have waited 6 years to have a child and we couldn't be happier, or more devoted parents. But I seriously feel depressed. I have these fantasies of running away or something crazy. What is wrong with me. Do any other parents ever feel this way?? I just miss my baby and all the time we used to spend laughing and playing. All I want to do is cry and cry. Help!
