What can help me cope

Concentration and relaxation techniques can help to control muscle groups and circulation throughout the body. The Increased relaxation and circulation achieved by these exercises can reduce the intensity of tinnitus in some patients.
Masking of tinnitus. 
Tinnitus is usually more bothersome in quiet surroundings. A competing sound at a constant low level, such as a ticking clock or radio static (white noise), may mask the tinnitus and make it less noticeable. Products that generate white noise are also available through catalogs and specialty stores.
Tinnitus maskers can be combined within hearing aids. They emit a competitive but pleasant sound that can distract you from the head noise. Some people find that a tinnitus masker may even suppress the head noise for several hours after it is used, But, this is not true for all users.
Hearing aids:
If you have a hearing loss, a hearing aid(s) may reduce head noise while you are wearing it and sometimes cause it to go away temporarily. It is important not to set the hearing aid at excessively loud levels, as this can worsen the tinnitus in some cases. However, a thorough trial before purchase of a hearing aid is advisable if your primary purpose is the relief of tinnitus.
