Old man can't appreciate change

I’ve been a little quite lately because a lot has been happening. So my company is currently in the process of merging with an important player in our industry, and as you might imagine, things are a tad messy at the moment. I am experiencing mixed feelings about all of this, one day I feel great that we were able to take it to this level and get noticed in the market, but sometimes I just cant it help but feel that I am letting myself down and selling out. I guess that anyone who has been emotionally involved in a project and has gone through a merger or acquisition would understand.
