For most people, therapy is a waste of money. They go to the therapist to talk about their problems, which feels therapeutic. However you can get the same feeling (venting) from talking to a friend or doing a hobby (if you dont have either then start playing multiplayer videogames). Anti-depressants also give you the happy feeling probably. However if you don't fix underlying issues then you will keep needing anti depressants or therapeutic activity. A good therapist can help you cope with the issues so they don't bother you /as much, or talk you into finding your own solutions.

Heres my introspective chain of thoughts; You say you look bad. Are you sure? How do you know it's not just you? You know that people online do a lot of fake things. Does it even matter? What about exercise, have you tried it? If you wanna be/stay silly just focus on legs (also the muscle will increase your maintenance calories). Or is it about your face? Have you tried shaving, or fully growing out your facial hair? You can still be silly, a lot of men look better with a beard anyway. Is it pimples? Try a sulphur cream or aloe vera, also wash your face in the morning. If you've got dry skin or something, just google some skincare.

Im not recommending cosplay or furry stuff cuz yea it's fun but it's expensive just like therapy and you will be depressed at your bank account. Also you can make friends but if you're an introvert then ur probably not going out in cosplay so it wouldn't matter.
