You need a ceph xray done. This will help you see things more clearly. But based on your pictures, it appears a class II profile. Some things:
1) I can't tell about maxillary deficiency. How is your bite? Did you ever have braces?
2) Your mandible is retrusive and BSSO would be needed to move it forward. There are much worse cases, but mine is like yours, and that's why I'm here.
3) Sliding genioplasty for the chin would also probably be indicated, but not sure
4) Perhaps more than anything, you need to lose excess body fat to lean out your face. Do not underestimate the importance of this. It would also help to better see your skeletal deficiencies.
