2 good options:: First is cognitive behavioral therapy which is very helpful for phobia. The second is exposure therapy.

CBT: Seek a cognitive-behavioral therapist who specializes in phobias. One method they use is systematic desensitization which slowly and incrementally brings the person closer and closer to the thing they are afraid of in slow, graduated steps that help make the anxiety more tolerable.

Find a psychologist: who specializes in Cognitive Behavioral therapy. They can do progressive desensitization in one or two sessions. They will teach you to relax, develop a hierarchy of your least to greatest fears. Then imagine them while relaxed. It is highly successful for all phobias

Anxiety: With proper therapy & patience, yes you can. Therapy involves cognitive therapy & behavior modification, relaxation, meditation & yoga, and use of anxiety medications for symptomatic relief.
