feeling jealous and envious.. gone suicidal

That may be. But there are people who do a lot for others.

Now, everyone is somewhat selfish in terms of looking out for his or her benefit.
Unfortunately, there are people who do not shy away from taking advantage of others.

Now what choices do you have?

Make friends for having relaxed good time.

Try to be realistic.

Don’t be so gullible for people to take advantage of you.

Make efforts to continue to do everything for your benefit in acceptable way.

Watch for others not to hurt you but don’t be paranoid. Just cautious.

Lastly, **help others, **(without getting yourself hurt).
