Nobody has a purpose in life. Belief that life has a purpose is a creationist delusion created to try and comprehend and apply order to what is intrinsically chaotic and random, and to fight the anxiety that their fears induce.

Your options are to choose one of the following:

1. Acceptance. You can accept that life is meaningless and that it’s okay. This one’s my preference.
2. Denial. You can deny life’s meaninglessness and seek to find or create a purpose for yourself. This can range from something as simple as a hobby to as life changing as having a family or advocating for a cause.
3. Embrasure. Revel in the chaos and express yourself through it, doing whatever you want without thought it care. This is best exemplified by the fictional character of the Joker.
4. Oppression. Take up religion to crush understanding of reality and replace it with a delusion of supernaturally defined purpose. This is probably the most commonly used option, frequently forced upon people during childhood.
5. Opposition. Attempt to fight the reality or mask the effects of meaninglessness through other means, such as direct therapy, chemical dependency (not recommended), talking with friends/family, or through other methods not previously mentioned.

Understanding one’s place in the universe (insignificant, irrelevant, and temporary speck) is important to having an accurate impression of ones existence. Whether one can accept that and what one do with that understanding is unique to the individual.

I hope that helps - good luck.
