I concur with Christine's advice about going to a Speech Therapist. My surgery left my tongue unable to touch the roof of my mouth or even stick out. Most insurance will cover the speech therapy. It involves daily exercises but will make a significant difference in your recovery.
My prothodontist also made me a palate drop (like a denture but it artificially lowers the roof of my mouth so my tongue can touch it and make the right sounds).
With over a year of speech therapy and now a second custom palate drop, I can speak intelligibly as long as I speak slowly and the listener's native language is English. Still cannot be understood by overseas call centers or help desks so it's a good thing I can repair my computers myself and handle most software problems.(too bad there are not more call centers handled by Wendy who would understand me)
A major part of my job was oral advocacy and even my critics would acknowledge me as a "silver tongued devil", so I know how important it is to you to regain speech. My ego made me retire and I miss my prior eloquence but Christine's right about enjoying the life we do in fact live.
The good news is that your speech will definitely improve over the next year.
